Hi @ronttizz
Find similar issue #16946.

Issue title	A stacktrace with a disorienting message is shown for az apim api import
Create time	2021-02-16
Comment number	3

Possible solution:
The error message "can only concatenate str (not "NoneType") to str" is shown in both issues. In the existing issue, the error message is caused by not specifying the --specification-format parameter. Similarly, in the new issue, the error message is caused by a similar issue. The solution to the new issue is to specify the --specification-format parameter. You can check all the valid values for the --specification-format parameter by running "az apim api import -h".

Please confirm if this resolves your issue.
