Describe the bug When using “azure interactive shell” on local PC running Win10 Pro in Powershell/command prompt, all az commands retult in following error message:

az>> vm list ‘NoneType’ object has no attribute ‘write’ Traceback (most recent call last): File “C:\Users\troyd\AppData\Local\Temp\pip-install-_jje8pgf\azure-cli-interactive\azure\cli\command_modules\interactive\azclishell\app.py”, line 668, in cli_execute File “C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\Lib\site-packages\knack\output.py”, line 136, in out print(output, file=out_file, end=‘’) File “C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\Lib\site-packages\colorama\ansitowin32.py”, line 40, in write self.__convertor.write(text) File “C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\Lib\site-packages\colorama\ansitowin32.py”, line 141, in write self.write_and_convert(text) File “C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\Lib\site-packages\colorama\ansitowin32.py”, line 169, in write_and_convert self.write_plain_text(text, cursor, len(text)) File “C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\Lib\site-packages\colorama\ansitowin32.py”, line 174, in write_plain_text self.wrapped.write(text[start:end]) AttributeError: ‘NoneType’ object has no attribute ‘write’

Updated the version. this seems fine in the latest version (2.0.58)

Since this issue was created az interactive was moved to an extension. Since it is working correctly in the latest version of the CLI (and thus the latest version of the extension), I will close this issue.
