NOTE: This was also repro'd by Az CLI Team, when reported in Internal Teams channel
The command fails with the following error
The command failed with an unexpected error. Here is the traceback:

Additional context

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
azure-cli-core 2.30.0.post20211112091047 requires requests[socks]~=2.25.1, but you have requests 2.26.0 which is incompatible.

This issue is caused by the dependency conflicts introduced by PR #18931. And we already have a PR #19801 can solve this issue
We plan to release the fix PR on 12-07
