`az ad group show --group` breaks with group names that use `+` in v2.37

Related command az ad group show --group <group_name>

Describe the bug Prior to v2.37 of the azure-cli, this command would complete successfully: az ad group show --group some_group+ As of v2.37 that same command returns the following error: No group matches the name of 'some_group+'

If you execute the same command on another group that does not have the + in its name: az ad group show --group some_group …then the command completes successfully.

To Reproduce

1. Ensure az --version returns a version < 2.37.
2. az ad group show --group some_group+ - command successful.
3. Upgrade azure-cli to version 2.37.
4. az ad group show --group some_group+ - command fails.

Further, no amount of shell escaping results in success:

• az ad group show --group "some_group+" - command fails.
• az ad group show --group 'some_group+' - command fails.
• az ad group show --group some_group\+ - command fails.

Expected behavior I suspect this behavior is a result of the recent move from the Active Directory Graph API to the Microsoft Graph API when upgrading to v2.37 of the azure-cli. That said, I think there is a reasonable expectation that rules around illegal characters should at least be harmonized between the two graphs before migrating from one to the other.

I found no mention of this behavior in the documentation I was able to locate on the differences between the two graphs.

Environment summary Experienced in Azure Cloud Shell which recently upgraded azure-cli to v2.37, and also in an installed azure-cli instance on a Manjaro Linux workstation.

az ad group show internally uses $filter query parameter to find groups.

It seems $search follows a different pattern that does allow + to be un-encoded.

$ az rest --url 'https://graph.microsoft.com/v1.0/groups?$search="displayName:azure-cli-test+"' --headers ConsistencyLevel=eventual --debug
cli.azure.cli.core.util: Request URL: 'https://graph.microsoft.com/v1.0/groups?$search=%22displayName:azure-cli-test+%22'

Anyway, I will fix the encoding issue in https://github.com/Azure/azure-cli/pull/22739.
