I beleive this is releated to the issue we have, using the AzureCLI@2 task. We can get servicePrincipalId, idToken, and tenantId but servicePrincipalKey is not set into the environment. This started today, and we had to update AzureAppConfiguration@10 in other pipelines, as AzureAppConfiguration@8 was not available anymore.

having the same issue, using AzureAppConfiguration@6 until this morning with no issue

[MaryanneNjeri]

After doing some investigation of the error A task is missing. The pipeline references a task called 'AzureAppConfiguration' with version 'x'. This indicates that the specific task version can not be found we also realized that the extension task name somehow got updated to AzureAppConfiguration.azure-app-configuration-task.custom-build-release-task.AzureAppConfiguration after the built in task was deployed which I suspect could be causing the extension task to go missing.

We are currently looking into resolving the issue for the missing task for older versions

[KristofKuli]

So using the old task name would make it possible to use the old versions?

[MaryanneNjeri]

Version 10 had to be removed to restore the functionality of previous versions and we have updated the guidance here to reflect this.

@KristofKuli just following are you still experiencing this issue ?
