Error: '500' 'Expecting value: line 1 column 1 (char 0)'

[VaidotasSm]

I get error without much explanation or debug info of whats going on and what needs fixing.

Error: '500' 'Expecting value: line 1 column 1 (char 0)'

Expected Behavior

• Some sort of useful information should be provided or more debug output e.g. printed response.
• Maybe improve docs of how to run cloned repo locally.

Current Behavior

I get following, not very informative output:

Onelogin Username: ...
Onelogin Password: ...
Google Authenticator Token: ...
Traceback (most recent call last):
  File ".../.pyenv/versions/3.7.7/bin/onelogin-aws-login", line 10, in <module>

    desc=self.ol_client.error_description
Exception: Onelogin Error: '500' 'Expecting value: line 1 column 1 (char 0)'

Also, tried to clone and debug locally, following instructions under Developing onelogin-aws-cli, however as someone with zero Python experience I get:

python3 onelogin_aws_cli/cli.py
Traceback (most recent call last):
  File "onelogin_aws_cli/cli.py", line 8, in <module>
    from onelogin_aws_cli import DEFAULT_CONFIG_PATH, OneloginAWS
ModuleNotFoundError: No module named 'onelogin_aws_cli'

So I think a little bit more beginner friendly documentation of how to run locally should be added too.

Steps to Reproduce

1. export ONELOGIN_AWS_CLI_DEBUG=1
2. onelogin-aws-login
