Fields of type"typing.Annotated" are not supported in pydantic

[kashyab12]

#490

Reproduced the issue with pydantic==1.7.4. After looking at the pydantic changelog v1.8 2021-02-26 introduced support for typing.Annotated hints on model fields. After installing pydantic==1.8 and trying to reproduce the issue, no errors were produced.

Thanks! In the github yaml files, the pydantic version is hardcoded for the unit tests, can you set it to 1.8.0 instead of just 1.* so that our unit tests run with the oldest version possible? Thanks!

@gabrieldemarmiesse after modifying the pydantic version in the github jobs, lots of tests are failing. Upon taking a look at the stacktrace seems like the pydantic object is missing the __version__ attribute. This issue was fixed in version 1.9 according to the changelog. So either:

• We modify the job to use version 1.9 (not the oldest version), which wouldn't tell us whether a new change breaks compatability with version 1.8; or
• Modify both minimum supported version and job version to use 1.9; or
• Modify references to __version__ and obtain the version by some other means.

We can se the minimul version to 1.9. That why we have our CI!

@gabrieldemarmiesse I've updated CI to use pydantic==1.9.
