Description

from pydantic.typing import evaluate_forwardref, get_args, get_origin
ImportError: cannot import name 'get_args' from 'pydantic.typing' (/Users/yfeng/Library/Caches/pypoetry/virtualenvs/aips-cq-resource-api-F3u0rVOe-py3.8/lib/python3.8/site-packages/pydantic/typing.cpython-38-darwin.so)

In fastapi=0.95.2, the dependency on pydantic is here which indicates pydantic=1.6.2 can be used. But get_args is only available in pydantic>=1.7, while pydantic=1.6.2 code doesn't have this
