E   If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.

E    1. Downgrade the protobuf package to 3.20.x or lower.

E    2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

Solutions:

• set protobuf>=3.0,<4.21
• write more compat code 🤷
