Issue Description
We are an internal Microsoft team and we are using the AzureFunctionApp@1 task to deploy our Function Apps in Azure. The issue consists in that many deployments of the App fail due to timeouts and failed retries.
It seems that the request to update the Function App package gets stuck and timeouts after around 3 mins (I guess this timeout is configured inside the task code) and after each timeout retries the request. This is retried several times and at the end, the task fails after 15-16 mins.
What we see in the task log is this:
This produces two issues:
- First, the deployment fails.
- Second, the Function App is left in a corrupted state where the new package has not been fully deployed, and the previous deployment is also broken, which results in the Function App not working anymore and required manual intervention.
We would like to know the root cause of this issue and also if it is possible to have some control from the AzureFunctionApp@1 input parameters to determine the duration of the timeouts and also the number of retries.
Also, the logs don't provide much detail on what the actual problem is.
