Errors when using WorkloadIdentityFederation auth scheme

[freerangeeggs]

With the introduction of Workload Identity Federation to Azure Pipelines (currently in preview) we've hit an error when running this pipeline task.

Logging in using ApplicationTokenCredentials, authScheme is 'WorkloadIdentityFederation'
Unhandled exception during ARM Outputs Task Error: secret must be a non empty string.

##[error]Error: secret must be a non empty string.

We've reverted as we were testing the preview, but assuming this feature will eventually come out of preview I'd say it will need to be covered.

Thank you.

Adding a +1 to this

Noted that it is currently in public preview, so reverted back until it is production release

MS document on the feature found here: Connect to Microsoft Azure with an ARM service connection

Cheers.

This is an open issue for us as well. All of the native Azure tasks for pipelines supports this functionality so I expect it will continue to be supported into the future.
