Flask + flask-restful gives strange error
This worked for me:
Add ERROR_404_HELP=False in your environment:
app.config['ERROR_404_HELP'] = False
I had similar problems related to trailing slashes, e.g. i defined api.com/endpoint and was sending request to api.com/endpoint/ and was having 404 errors.
Solution was to configure Flask application not to be strict about trailing slashes by: app.url_map.strict_slashes = False
