[Siecje]

  from collections import Mapping, OrderedDict

Has this issue been fixed?

[Siecje]

Yes. https://github.com/graphql-python/graphene/blob/master/graphene/types/field.py#L2

I created the issue and then went to fix it and it was already correct.

Thanks! Just realized after taking a look. @Siecje

Confirmed, this is still happening in graphene 2.1.8 (using Python 3.8.1)

This is fixed in version 3.0 if you have a look at the tags.

Any chance this could be released in the 2.* series? Since 3.0. is not yet released this is blocking our update to Python 3.9
