Exception after upgrading to version 0.19.0 and 0.19.1

Hi,

Python beginner here after updating to version 0.19.0 and 0.19.1 i get the following error when trying to run the Flask server. I don’t know much else than to include the traceback.

Traceback (most recent call last):
  File "/Users/xyz/project1/api.py", line 65, in <module>
    api.register_blueprint(blueprint.bp)

I am using Python version 3.7.6 and I really like your library

Thanks, i’ll look into that.

Can confirm 0.19.2 works again for my case.

I’m not sure what you’re trying to achieve, but you shouldn’t have to do that.

The point of the 0.19 release is to auto-document error responses when possible. 422 errors are automatically documented already.

If you need to generate 422 errors inside your view function, just call abort(422, errors={optional error structure}) and you’re done. No need for you to declare an error schema.

Hopefully, this issue should be fixed and you should be able to see the errors described in the doc.

If you need a different error schema you may have to override stuff in the error handler.
