az apic service returns 400 Bad Request when importing APIs from APIM

# Description

When trying to import APIs from an APIM instance into APIC using Azure CLI's ```az apic import-from-apim``` command in PowerShell, the result is always a 4000 BAD REQUEST with an error ```Object reference not set to an instance of an object```. I just installed the extension today to work with apic, so it should be a newer version.

# Reproduction steps

Steps to reproduce the behavior:

1. Retrieve the APIM ID
2. Concatenate "/apis/*" to the end of the APIM ID into a new var $apiIDs
3. Execute the command ```az apic service import-from-apim --service-name --resource-group --source-resource-ids $apiIDs```

# Expected behavior

The APIs should import.

# Actual behavior

Always receive a 400 BAD REQUEST with an "Object reference not set to an instance of an object" error.

# Screenshots

If applicable, add screenshots to help explain your problem.

# Additional context

Just installed the APIC extension today, so the version is newer. Followed the examples in the APIC import from APIM Microsoft Documentation.
