Last working task version

Regression Description

We use AzureFunctionApp@1 to deploy a function app on Linux from a pipeline which runs on ubuntu-latest agent. We didn't make any code or deployment or pipeline related changes. But it started to fail with the following error:
"Error: Error: Failed to deploy web package to App Service. Unauthorized (CODE: 401)"

ZIP Deploy response: {"statusCode":401,"statusMessage":"Unauthorized","headers":{"content-length":"0","date":"Sat, 07 Sep 2024 20:50:20 GMT","www-authenticate":"Basic realm="site""}}

I tried upgrading to AzureFunctionApp@2 but still seeing the same error.

We use this task with a service connection setup using workload identity federation. The identity used to deploy already has Reader, Contributor and UAA roles on the subscription.
