Can't run any az commands: Blank `cli.azure.cli.core.util` error

Describe the bug I was fine running 2.2.0 and decided to upgrade recently, but now I can’t get anything to work at all.

All commands that do any talking to Azure respond with: cli.azure.cli.core.util : and literally no error output other than that (in the --debug --verbose logs).

Is there anything I can do to get any more detailed logs?

On further exploration az rest works, for example: az rest --method get --uri https://management.azure.com/subscriptions/<sub id>/providers/Microsoft.Storage/storageAccounts?api-version=2019-06-01

To Reproduce Any az command that talks to Azure, such as az storage account list.

Expected behavior az should work.

Environment summary Windows 10 Cygwin 3.1.4 Python 3.6

I’ve tried various versions of the CLI 2.4.0, 2.3.0, 2.2.0, and also a known working from source installed into a venv, all fail with the same errors.

I’ve also tried re-installing python and pip through the Cygwin setup, and I’ve tried removing and reinstalling all pip packages after that too.

(P.S. Nope I don’t want to use WSL, WSL is hacky compared to Cygwin 🙂)

@qianwens why has this been closed without comment?

Deleting the .azure folder is nothing more than a workaround - the underlying issue remains to be fixed, or at the very least in the interim, a meaningful error message would be helpful 😕

As it’s no longer a Cygwin problem I thought about the only thing that Windows Python 2, Cygwin Python 3, and Cygwin Python 3 with venv share, which is the ~/.azure directory.

I moved my ~/.azure directory out of the way and re-logged in and the commands now seem to be working again.

Is there anyway we can debug why it fails with my current ~/.azure directory?

It might be nice to get a better error message out of it than nothing, and just me starting again?
