Unsupported typing: typing.Dict

[HerrMuellerluedenscheid]

Hey,

This problem occurrs after updating from xsdata 21.4 to 21.5:

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/xsdata/formats/dataclass/models/builders.py", line 408, in analyze_types
    types = evaluate(type_hint, globalns)

    return tuple(_evaluate(_eval_type(tp, globalns, localns)))

    origin = get_origin(tp)
  File "/usr/local/lib/python3.8/site-packages/xsdata/formats/dataclass/typing.py", line 17, in get_origin
    raise TypeError()
TypeError

During handling of the above exception, another exception occurred:

xsdata.exceptions.XmlContextError: Unsupported typing: typing.Dict

Not sure where that is rooted exactly but I'll try to dig into it soon.

If you use the code generator re-run it against your schema, otherwise replace all Dict typing with explicit arguments

xxx: Dict = field(... with xxx: Dict[str, str] = field(...

Currently for dictionaries only str,str arguments are supported, but I plan to extend this in the future.

Hi @HerrMuellerluedenscheid , a fix to treat bare Dict annotations as Dict[str, str], practically reverting to the original behavior was merged on master and will be included in the next release

Thank you
