Linked ARM Templates failing - azure-resource-manager

Question

Linked ARM Template for API management failing
I deployed each template individually in sequence in the same sequence as they are deployed successfully.
"resources": [
{
"apiVersion": "2017-05-10",
"name": "instanceTemplate",
"type": "Microsoft.Resources/deployments",
"properties": {
"mode": "Incremental",
"templateLink": {
"uri": "url for template",
"contentVersion": "1.0.0.0"
},
"parameters": {
"sku": { "value": "[parameters('APIManagementSku')]" },
"skuCount": { "value": "[parameters('APIManagementSkuCapacity')]" },
"publisherName": { "value": "[parameters('publisherName')]" },
"publisherEmail": { "value": "[parameters('publisherEmail')]" }
}
}
},
{
"apiVersion": "2017-05-10",
"name": "productsUsersTemplate",
"type": "Microsoft.Resources/deployments",
"properties": {
"mode": "Incremental",
"templateLink": {
"uri": "url for template",
"contentVersion": "1.0.0.0"
},
"parameters": {
"apiManagementServiceName": { "value": "[parameters('APIManagementInstanceName')]" }
}
},
"dependsOn": [
"[resourceId('Microsoft.Resources/deployments', 'instanceTemplate')]"
]
},
{
"apiVersion": "2017-05-10",
"name": "seviceTagsTemplate",
"type": "Microsoft.Resources/deployments",
"properties": {
"mode": "Incremental",
"templateLink": {
"uri": "url for template",
"contentVersion": "1.0.0.0"
},
"parameters": {
"apiManagementServiceName": { "value": "[parameters('APIManagementInstanceName')]" }
}
},
"dependsOn": [
"[resourceId('Microsoft.Resources/deployments', 'instanceTemplate')]"
]
}
]
I expect the template to be correctly deployed (As they do when deploying them individually).
However, I get the following error message:
Conflict: {
"status": "Failed",
"error": {
"code": "ResourceDeploymentFailure",
"message": "The resource operation completed with terminal provisioning state 'Failed'.",
"details": [
{
"code": "DeploymentFailed",
"message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-debug for usage details.",
"details": [
{
"code": "PreconditionFailed",
"message": "{\r\n \"error\": {\r\n \"code\": \"PreconditionFailed\",\r\n \"message\": \"Exception of type 'Microsoft.WindowsAzure.ApiManagement.Management.Core.Exceptions.PreconditionFailedException' was thrown.\",\r\n \"details\": null\r\n }\r\n}"
}
]
}
]
}
}
I also tried adding additional dependencies but I still get the same error
