My Web API method returns a binary PDF file in the response body and I've set this in the swagger file in the Custom Connector of Power Automate. However, despite the output being a binary PDF file AND that the property type is "file", the Test function in the Custom Connector UI still thinks its returning a "string" even through it clearly isn't!
Question: Any ideas what I'm doing wrong to make the tester think it's a string?
Here is a screenshot of the issue:
Here is my swagger for the Web API method (take note of the 200 response of schema: {type: file, format: binary}:

Error: Invalid State Machine Definition: 'SCHEMA_VALIDATION_FAILED: The value for the field 'Date.$' must be a valid JSONPath at /States/Insert Data Dynamodb/Parameters' (Service: AWSStepFunctions; Status Code: 400; Error Code: InvalidDefinition;
below is the corresponding serverless.yaml code.
I tried wrapping the two parameters into encoded json string and passed it as single payload field and it resulted in the same error but when there is only one plain field in the payload this code deployed successfully
Any suggestions on how to pass two parameters?

End: true
Your Date.$ property has value of ${self:custom.dates.year}${self:custom.dates.month}${self:custom.dates.day}. Let's assume that:
const dates = {
"year": "2000",
"month": "01",
"day": "20"
}
The result will be Date.$: "20000120" which is not a valid JSON Path.
JSON Path needs to start with a $ sign and each level is divided by ..
Do you want to achieve something like this? $.2000.01.20?
As you see, the issue is not with passing 2 parameters but with wrong string JSON Path created by string interpolation for Date.$.

I'm trying to define a post endpoint using swagger, but it isn't allowing the requestBody parameter:
/names/{roster}:
get:
#...
post:
x-swagger-router-controller: names
description: Adds or removes name(s)
operationId: manageNames
parameters:
- name: roster
in: path
description: the roster to use
type: string
required: true
requestBody:
content:
'application/json':
schema:
$ref: '#/definitions/ManageNamesRequest'
when I run npm start, I get this:
API Errors:
#/paths/~1names~1{roster}/post: Additional properties not allowed: requestBody
1 error and 0 warnings
What's wrong with my spec?
You are probably mixing OpenAPI/Swagger 2.0 and OpenAPI 3.0 syntax. Your spec seems to be 2.0, but the requestBody keyword is a 3.0 feature. In 2.0, the request body is defined as a body parameter:
paths:
/names/{roster}:
post:
produces:
- application/json
...
parameters:
- ...
- in: body
name: body
required: true
schema:
$ref: '#/definitions/ManageNamesRequest'

I'm writing a service with a GET that can return one of five different but closely related types. Since the user wants the option of searching through all five types at once, it has to be a single get call. I'm returning JSON, which can easily handle any type.
I'm trying to do this in Swagger, using their polymorphism feature, which I've never tried before. I'm doing it just like in the example, except under "definitions" instead of "components/schemas". But I'm getting a strange error message that I can't understand. The swagger file is below. The error says this:
Schema error at definitions['Event'].discriminator should be string
It gives this on line 49, which says discriminator:
So, my two questions are: How can I fix it? And will this even give me what I need?

The error occurs because you are mixing OpenAPI 2.0 and 3.0 syntax.
Your spec is swagger: '2.0' but the following is 3.0 syntax:
discriminator:
propertyName: eventType
In OpenAPI 2.0, the value of discriminator is the property name:
discriminator: eventType
Also, OpenAPI 2.0 assumes that the possible values of the discriminator property (in this case eventType) are exactly the same as the model names in definitions. That is:
If eventType can be event, partner etc. in lowercase, then the model names must also be in lowercase – event, not Event.
If eventType is some code like e, p, d etc., the model names must be e, p, d etc. instead of Event, Partner etc.

Your second parameter has an invalid "in" value, it should be formData.
According to Swagger specification:

I am try to create a swagger file with the following path:
paths:
/v1/customers/{id}/summary :
However I get the following error right off bat:
API requires path parameter but it is not defined: id
at paths ▹ /v1/customers/{id}/summary
It does not seem to like the 'id' parameter. Could anybody tell me how I could rectify this?
If I drill down on this I see the following:
Details
Object
swaggerError: Object
errors: Array [1]
0: Object
code: "MISSING_API_PATH_PARAMETER"
message: "API requires path parameter but it is not defined: id"
data: "/v1/customers/{id}/summary"
path: Array [2]
warnings: Array [0]
Basically, you're declaring a path that has a path parameter in it, by using path templates. In this case {id} declares a path parameter called id.
When you declare such a path, it means that you have to declare that path parameter as part of the operation.
Take a look at this YAML example:
/pets/{id}:
get:
description: Returns a user based on a single ID, if the user does not have access to the pet
operationId: findPetById
produces:
- application/json
- application/xml
- text/xml
- text/html
parameters:
- name: id
in: path
description: ID of pet to fetch
required: true
type: integer
format: int64
responses:
'200':
description: pet response
schema:
$ref: '#/definitions/pet'
default:
description: unexpected error
schema:
$ref: '#/definitions/errorModel'
You can see there's an {id} in the path, and a corresponding id parameter definition. Without it, the spec won't be valid.
