Payload for authV2 running in Azure DevOps Pipelines invalid

[Tom-CT]

Describe the bug

I am trying to use az ad app update --id [appId] --set api=[json] to add a scope to an app registration. Locally I am using powershell 7.4.6, cli 2.67.0 and authV2 0.1.3 on win 24H2.

The following is the code used to reproduce the issue:

$scopeId = [guid]::NewGuid().Guid
$userImpersonationScope = [ordered]@{
    adminConsentDescription = "user impersonation"
    adminConsentDisplayName = "user_impersonation"
    id                      = "$scopeId"
    isEnabled               = "true"
    type                    = "User"
    userConsentDescription  = "user impersonation"
    userConsentDisplayName  = "user_impersonation"
    value                   = "user_impersonation"
}

Write-Host "user_impersonation permission scope not found - creating with id: $scopeId"

$update = @{
    oauth2PermissionScopes = @($userImpersonationScope)
}
$updateJson = ConvertTo-Json $update -Depth 4 -Compress 
$escapedJson = ConvertTo-Json $updateJson

az ad app update --id $appId --set api=$updateJson

If I run this locally, I get a 200 and adding the --debug flag to the az command, I can see there's a payload that looks like:

{"api": {"oauth2PermissionScopes": [{"adminConsentDescription": "user impersonation", "adminConsentDisplayName": "user_impersonation", "id": "[some guid]", "isEnabled": "true", "type": "User", "userConsentDescription": "user impersonation", "userConsentDisplayName": "user_impersonation", "value": "user_impersonation"}]}}

If I run the same thing in an Azure Pipeline on a windows-latest agent, I get a 400 and can see it has a payload that looks like:

{"api": "{\"oauth2PermissionScopes\":[{\"adminConsentDescription\":\"user", "impersonation\",\"adminConsentDisplayName\":\"user_impersonation\",\"id\":\"[some guid]\",\"isEnabled\":\"true\",\"type\":\"User\",\"userConsentDescription\":\"user": "", "impersonation\",\"userConsentDisplayName\":\"user_impersonation\",\"value\":\"user_impersonation\"}]}": ""}

I have added additional logging in and can confirm that $updateJson and $escapedJson are identical when running locally and in the pipeline. I have also checked that the service connection that the pipeline is using for the AzureCLI@2 task this is running in has sufficient privileges to view and modify registered applications.

The only difference I can really see is that I have the authV2 extension installed locally, but to ensure that it is being used by the pipeline, I have this towards the top of my script:

az extension add --name authV2

Related command

az ad app update --id [appId] --set api="{\"oauth2PermissionScopes\":[{\"adminConsentDescription\":\"user impersonation\",\"adminConsentDisplayName\":\"user_impersonation\",\"id\":\"[some guid]\",\"isEnabled\":\"true\",\"type\":\"User\",\"userConsentDescription\":\"user impersonation\",\"userConsentDisplayName\":\"user_impersonation\",\"value\":\"user_impersonation\"}]}"

Expected behavior

authV2 should have a payload of when running under the AzureCLI@2 task:

{"api": {"oauth2PermissionScopes": [{"adminConsentDescription": "user impersonation", "adminConsentDisplayName": "user_impersonation", "id": "[some guid]", "isEnabled": "true", "type": "User", "userConsentDescription": "user impersonation", "userConsentDisplayName": "user_impersonation", "value": "user_impersonation"}]}}

Hi @Tom-CT,

2.67.0 is not the latest Azure CLI(2.68.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

Thank you for opening this issue, we will look into it.

I don't think this is related to authV2 extension. This is actually PowerShell quoting issue #15529.

The values of $updateJson and $escapedJson are:

> $updateJson
{"oauth2PermissionScopes":[{"adminConsentDescription":"user impersonation","adminConsentDisplayName":"user_impersonation","id":"6504e98c-0c83-424a-a0cc-7c8e4dbb5999","isEnabled":"true","type":"User","userConsentDescription":"user impersonation","userConsentDisplayName":"user_impersonation","value":"user_impersonation"}]}

> $escapedJson
"{\"oauth2PermissionScopes\":[{\"adminConsentDescription\":\"user impersonation\",\"adminConsentDisplayName\":\"user_impersonation\",\"id\":\"6504e98c-0c83-424a-a0cc-7c8e4dbb5999\",\"isEnabled\":\"true\",\"type\":\"User\",\"userConsentDescription\":\"user impersonation\",\"userConsentDisplayName\":\"user_impersonation\",\"value\":\"user_impersonation\"}]}"

When executed locally in PowerShell 7.4.6 on Windows, \ is interpreted by CMD to escape ":

> az --debug $escapedJson
cli.knack.cli: Command arguments: ['--debug', '{"oauth2PermissionScopes":[{"adminConsentDescription":"user impersonation","adminConsentDisplayName":"user_impersonation","id":"6504e98c-0c83-424a-a0cc-7c8e4dbb5999","isEnabled":"true","type":"User","userConsentDescription":"user impersonation","userConsentDisplayName":"user_impersonation","value":"user_impersonation"}]}']

In CMD, the escaping also works as expected:

>az --debug "{\"oauth2PermissionScopes\":[{\"adminConsentDescription\":\"user impersonation\",\"adminConsentDisplayName\":\"user_impersonation\",\"id\":\"[some guid]\",\"isEnabled\":\"true\",\"type\":\"User\",\"userConsentDescription\":\"user impersonation\",\"userConsentDisplayName\":\"user_impersonation\",\"value\":\"user_impersonation\"}]}"

cli.knack.cli: Command arguments: ['--debug', '{"oauth2PermissionScopes":[{"adminConsentDescription":"user impersonation","adminConsentDisplayName":"user_impersonation","id":"[some guid]","isEnabled":"true","type":"User","userConsentDescription":"user impersonation","userConsentDisplayName":"user_impersonation","value":"user_impersonation"}]}']

However, in PowerShell on Linux, CLI is receiving

> az --debug $escapedJson                                                                                                                                                    
cli.knack.cli: Command arguments: ['--debug', '"{\\"oauth2PermissionScopes\\":[{\\"adminConsentDescription\\":\\"user impersonation\\",\\"adminConsentDisplayName\\":\\"user_impersonation\\",\\"id\\":\\"3088a995-16a4-4f95-8197-38dfe2280cea\\",\\"isEnabled\\":\\"true\\",\\"type\\":\\"User\\",\\"userConsentDescription\\":\\"user impersonation\\",\\"userConsentDisplayName\\":\\"user_impersonation\\",\\"value\\":\\"user_impersonation\\"}]}"']

This matches your observation on Azure DevOps Pipelines, so please check if you are using a Linux agent.

Actually, instead of escaping the JSON and passing it as a shell parameter, I highly recommend following https://github.com/Azure/azure-cli/blob/dev/doc/quoting-issues-with-powershell.md#best-practice-use-file-input-for-json to use stdin instead:

> echo $updateJson | az rest --url 'https://127.0.0.1' --method POST --body '@-' --debug
...
cli.azure.cli.core.util: Request body:
cli.azure.cli.core.util: {"oauth2PermissionScopes": [{"adminConsentDescription": "user impersonation", "adminConsentDisplayName": "user_impersonation", "id": "3088a995-16a4-4f95-8197-38dfe2280cea", "isEnabled": "true", "type": "User", "userConsentDescription": "user impersonation", "userConsentDisplayName": "user_impersonation", "value": "user_impersonation"}]}

This bypasses shell quoting and ensures the JSON is passed to Azure CLI untouched.

Thanks, using stdin definitely makes it easier and helped solve my issue
