With the release of version 5.0.0 of webargs, the behaviour of @use_kwargs and marshmallow.missing has change. For full explanation, see the changelog here.
Backwards-incompatible: Missing arguments will no longer be filled in when using @use_kwargs (#342, #307, #252). Use **kwargs to account for non-required fields.
This means that all conditions checking for is missing or is not missing needs to be re-checked and fixed, probably by adding the missing field with a value to the use_kwargs dict.
Example of one to be checked.
