Is there a way to get the actual command error stderr output when an error is returned?

[redragonx]

When running something in rust like:

       let data_result = run_fun!(cat $formatted_loc | /home/blah/test.py);

I can get a error like:

Custom { kind: Other, error: "Running [\"/home/blah/test.py\"] exited with error; status code: 1" }

Which is not detailed enough to understand what exactly the error is. If the above command is run manually via bash terminal, I get the following useful error from Python:

Traceback (most recent call last):
  File "./home/blah/test.py", line 31, in <module>
    if 'awesome_thing' in res['things']:
TypeError: 'NoneType' object is not subscriptable

How can I get the Python error instead of the generic error?

After reviewing existing issues, this works for me, we need more documentation on ignore and redirection.

let data_result = run_fun!(ignore cat $formatted_loc | /home/blah/test.py 2>&1);
