Describe the bug Our release pipeline runs on hosted Azure DevOps agents. Releases that worked fine yesterday, do not work anymore. It looks like the DevOps agents have upgraded azure-cli from 2.9.1 to 2.10.1.

The scripts are run on Powershell Core running on ubuntu-20.4 agents, but I have also tried ubuntu-18.04.

To Reproduce Upgrade azure-cli from 2.9.1 to 2.10.1 and use az webapp create

Expected behavior No errors

@calvinsID thank you for your fast response. When can we expect azure-cli 1.10.2 to be available on the Azure DevOps agents? In the meantime what can I do to workaround this issue?
