Show powershell errors in flask-wtf web form

Have you read through the subprocess.run documentation? A lot of your questions are answered here:

https://docs.python.org/3/library/subprocess.html

You need to check if there was an error. You are using check, but I would just look at the return code. If there was an error, return some markup that contains the error info that can be displayed on the web page.

result = subprocess.run(..., check=False)
if result.returncode != 0:
    return some_markup_containing_result.stderr
elif result.stdout:
    return some_markup_containing_result.stdout
else:
    return something else?
