Strongloop loopback: how to set up a model to store multimedia? - multimedia

Could someone give me an example of a model named "Multimedia.json" that I could use to store uploaded multimedia files (audio, video, or jpg)? Specifically, is there a type called "multimedia" or "binary"? Any strategies the Strongloop way?
Thanks,

There is no built in way to do this, but StrongLoop themselves refer to this post in their documentation for the current best method to store metadata with the storage component.

The language expression property '0' can't be evaluated, property name must be a string - ARM Template error while adding Key Vault access policy

I've been working on an issue and seem to be stuck, so asking on so in case anyone can help.
To describe the issue, I've got an existing Azure Key Vault setup, and wish to add a number of access policies to this resource group. It needs to be conditional as if the function name is "false" then that function should not be added to key vault access policy.
variable section:
"variables": {
"functionAccess": {
"value": [
{
"name": "[parameters('Function_1')]"
},
{
"name": "[parameters('Function_2')]"
},
{
"name": "[parameters('Function_3')]"
}
]
}
}
My Template :
{
"apiVersion": "2016-10-01",
"condition": "[not(equals(variables('functionAccess')[CopyIndex()].name, 'false'))]",
"copy": {
"batchSize": 1,
"count": "[length(variables('functionAccess'))]",
"mode": "Serial",
"name": "accessPolicies"
},
"name": "[concat(parameters('KeyVault_Name'), '/add')]",
"properties": {
"accessPolicies": [
{
"tenantId": "[subscription().tenantId]",
"objectId": "[if(not(equals(variables('functionAccess')[CopyIndex()].name, 'false')), reference(concat('Microsoft.Web/sites/', variables('functionAccess')[CopyIndex()].name), '2016-08-01', 'Full').identity.principalId, json('null'))]",
"permissions": {
"keys": [
"get",
"list"
],
"secrets": [
"get",
"list"
],
"certificates": [
"get",
"list"
]
}
}
]
},
"type": "Microsoft.KeyVault/vaults/accessPolicies"
}
When I deploy my ARM template for the azure key vault I got this error message:
The language expression property '0' can't be evaluated, property name must be a string.
also tried below, but same error:
{
"apiVersion": "2018-02-14",
"name": "[concat(parameters('KeyVault_Name'), '/add')]",
"properties": {
"copy": [
{
"batchSize": 1,
"count": "[length(variables('functionAccess'))]",
"mode": "serial",
"name": "accessPolicies",
"input": {
"condition": "[not(equals(variables('functionAccess')[copyIndex('accessPolicies')].name, 'false'))]",
"tenantId": "[subscription().tenantId]",
"objectId": "[if(not(equals(variables('functionAccess')[copyIndex('accessPolicies')].name, 'false')), reference(concat('Microsoft.Web/sites/', variables('functionAccess')[copyIndex('accessPolicies')].name), '2016-08-01', 'Full').identity.principalId, json('null'))]",
"permissions": {
"keys": [
"get",
"list"
],
"secrets": [
"get",
"list"
],
"certificates": [
"get",
"list"
]
}
}
}
]
},
"type": "Microsoft.KeyVault/vaults/accessPolicies"
}
There are a few options for dealing with filtering an array for copy operation. I deploy my ARM templates from PowerShell scripts and use PowerShell to setup parameter values. When I need special logic handle different inputs for different environments, I let PowerShell handle it.
If you must handle the filtering in ARM and you have the option to input a CSV list of functions, then perhaps the following will work. You can then use the functionAccessArray to iterate over in the copy operation.
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
},
"variables": {
"functionAccessCsv": "Function-0,Function-1,false,Function-4,false,Function-6,Function-7",
"functionAccessFiltered": "[replace(replace(variables('functionAccessCsv'), 'false', ''), ',,', ',')]",
"functionAccessArray": "[split(variables('functionAccessFiltered'), ',')]"
},
"resources": [
],
"outputs": {
"functionAccessCsvFiltered": {
"type": "string",
"value": "[variables('functionAccessFiltered')]"
},
"functionAccessArray": {
"type": "array",
"value": "[variables('functionAccessArray')]"
}
}
}
The result:
I just had the same issue. By using an array parameter with a default value instead of a variable, I got it to work.
"parameters": {
"functionAccess": {
"type": "array",
"defaultValue": [
"value1",
"value2",
"value3"
]
}
}

Internal server error when deploying ARM Template

I am deploying an arm template that contains the following resources
Microsoft.Storage/storageAccount
Microsoft.Sql/servers
Microsoft.Sql/servers/auditPolicies
Now everything worked until I started changing the values for the auditPolicies object. Here are the steps I took until the InternalServerError occurred.
Added the auditState property and set its value to Disabled. Deployment Successful.
Changed the auditState property to Enabled. Deployment failed. Error states that the storageAccountName is required.
Added storageAccountName and set its value to the name of the storage account. Deployment failed. Error states that storageAccountKey.
Added storageAccountKey and set its value to key1 of the storage account's keys object. Deployment failed. Internal Server Error - "An Error has occurred while saving Auditing settings, please try again later". Additionally, the errors cause the deployment to run indefinitely. Though I am not concerned about that aspect.
The following is the complete template.

What am I missing that will help resolve this issue? What do I need to do to stop this internal server error?
I have added the complete template as was requested by #Pete
I have found the answer after connecting with Azure Support.
The resource type: Microsoft.Sql/servers/auditingPolicies is no longer supported and in the next few weeks Azure Resource Manager will no longer support this completely.
This resource type refers directly to table auditing, which has been reported as being deprecated for blob auditing. Though the documentation at this time does not directly report it. The docs will be updated in the coming days after this post, by the owners.
To enable the auditing you need to use the Microsoft.Sql/servers/auditingSettings object. The documentation on this is coming and until it does you will be directed to documentation for the database version of this resource type Microsoft.Sql/servers/databases/auditingSettings.
Auditing settings work much like the Auto-Tuning advisors. You can set either server or database level settings. The server settings will be inherited by the database if the database has not been configured directly.
This is a sample of the auditingSettings object that I use instead of the auditingPolicies object above. It is nested just the same.

Hosting my own service (.NET) - what is a valid response for Alexa?

I'm hosting my own service (HTTPS) on Azure - I have selected 'my endpoint is a subdomain with a wildcard cert'
I'm using Alexa.NET to craft the response.
I can verify that the simulator is hitting my endpoint (I did remote debugging and saw the breakpoint was hit) and I know that my endpoint is returning this (I tried it in Postman)
{
"Version": "1.0",
"SessionAttributes": null,
"Response": {
"OutputSpeech": {
"Type": "PlainText",
"Text": "test successful"
},
"Card": null,
"Reprompt": null,
"ShouldEndSession": true,
"Directives": []
}
}
I can't find any documentation on what the response is supposed to look like. I guess I can try creating the same thing with a lambda function...
Anyone have any suggestions on what I can try? This whole process of hosting my own service has been very frustrating...
Please find sample response format here https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/alexa-skills-kit-interface-reference#response-body-syntax

It was because my 'name's started with an uppercase. Friggin Javascript serializer....
But thanks Vijay for the pointer to the documentation.
In .NET mvc, this is how you make the property names lower case:
return JsonConvert.SerializeObject(alexaSkillResponse, new JsonSerializerSettings {
ContractResolver = new CamelCasePropertyNamesContractResolver()
});

Provide request header for Microsoft.Scheduler/jobCollections/jobs

I found information over Azure Portal but not in ARM Template under webjob Properties. How can reference information on the blue arrow over my ARM template ?
How can reference information on the blue arrow over my ARM template ?
If we want to get the publishingPassword, then we could use ListPublishingCredentials API in the ARM template via list function, list(concat('Microsoft.Web/sites/', parameters('websisteName') ,'/config/publishingcredentials'), '2016-08-01').properties.publishingPassword
According to your template, it seems the that you want to call WebJob REST API, If it is that case, the authorization header is base64(publishusername:publishpassword).
base64(concat(list(concat('Microsoft.Web/sites/', parameters('websisteName'),'/config/publishingcredentials'), '2016-08-01').properties.publishingUserName,':',list(concat('Microsoft.Web/sites/', parameters('websisteName') ,'/config/publishingcredentials'), '2016-08-01').properties.publishingPassword))
I write a demo to test it on my side, it works correctly .

copyIndex() inside a listKeys()

We're trying to deploy an ARM template which deploys a Stream Analytics job with n Event Hubs outputs depending on an input parameter.
Right now we're having success with all but the listKeys() function inside the outputs property copy loop function which gets each Event Hub's primary keys:
"sharedAccessPolicyKey": "[listKeys(resourceId('Microsoft.EventHub/namespaces/eventhubs/authorizationRules', variables('clientEventHubNamespace'), parameters('clients')[copyIndex('outputs')].id, variables('clientEventHubClientSharedAccessName')), '2015-08-01').primaryKey]"
We get the error:
17:44:31 - Error: Code=InvalidTemplate; Message=Deployment template
validation failed: 'The template resource
'tailor-router-axgf7t3gtspue' at line '129' and column '10' is not
valid: The template function 'copyIndex' is not expected at this
location. The function can only be used in a resource with copy
specified. Please see https://aka.ms/arm-copy for usage details..
Please see https://aka.ms/arm-template-expressions for usage
details.'.
However, if we change this to be a specific index:
"sharedAccessPolicyKey": "[listKeys(resourceId('Microsoft.EventHub/namespaces/eventhubs/authorizationRules', variables('clientEventHubNamespace'), parameters('clients')[0].id, variables('clientEventHubClientSharedAccessName')), '2015-08-01').primaryKey]"
it works.
Is copyIndex('propertyName') inside a listKeys() a supported function?
If not, is there a workaround that would achieve the same effect?
Kind regards,
Nick

Thanks for reporting this and sorry for the inconvenience.
I just talked to the ARM team, we had an issue when copyindex was inside the index tags eg 'array[copyindex()]'. It should be fixed now.
Let us know how it goes.
Thanks,
