Multiple scopes for Dapr Component in Container Environment can't be set using Bicep

[adrobson]

Bicep version
0.22.6

Describe the bug
The az cli gives the following error:
"The JSON value could not be converted to System.String.

To Reproduce

Use the following in a bicep file:

param containerAppsName string
param storageAccountName string
param storagekey string

param containers object[]

resource managedEnvironment 'Microsoft.App/managedEnvironments@2023-05-01' existing = {
  name: containerAppsName
}

resource storageBinding 'Microsoft.App/managedEnvironments/daprComponents@2023-05-01' = [for container in containers:  {
  name: container.daprComponentName
  parent: managedEnvironment
  properties: {
    componentType: 'bindings.azure.blobstorage'
    metadata: [
      {
        name: 'storageAccount'
        value: storageAccountName
      }
      {
        name: 'container'
        value: container.containerName
      }
      {
        name: 'decodeBase64'
        value: 'false'
      }
      {
        name: 'direction'
        value: 'input'
      }
      {
        name: 'publicAccessLevel'
        value: 'none'
      }
      {
        name: 'storageAccessKey'
        secretRef: 'storagekey'
      }
    ]
    scopes: [ 
      container.scopes
    ]
    secrets: [
      {
        name: 'storagekey'
        value: storagekey
      }
    ]
    version: 'v1'
  }
}
]

Use the following parameters.json:

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "setupNum": {
      "value": "006"
    },
    "containers": 
    {
        "value":
        [
            {
                "containerName":"containera",
                "daprComponentName":"bindinga",
                "scopes": ["appa", "appb"]
            },
            {
                "containerName":"containerb",
                "daprComponentName":"bindingb",
                "scopes": ["appa", "appc"]                    
            }
        ] 
    }
  }
}

Additional context
Add any other context about the problem here.
Hardwiring more than one value in the component does work but setting from array of strings in bicep or json file does not work

Can you share the full error response? From the error message, it is not clear if the issue is coming from the App RP or from the Template Deployments service.

Sorry I closed this accidentally.

[anthony-c-martin]

Should

scopes: [ 
  container.scopes
]

Instead be:

scopes: container.scopes

The error from the RP suggests to me that you're passing a non-string-value as the first entry in the array.

[adrobson]

Thanks that works.

[anthony-c-martin]

A minor refactoring suggestion would be to use:

type containerType = {
  scopes: string[]
  containerName: string
  daprComponentName: string
}

param containers containerType[]

Instead of:

param containers object[]

That way I think the editor could have probably caught the problem instead of it being caught when deploying (see here for an example)

[adrobson]

Thanks, great tip about types. I will use them in future. I didn't know they existed.
