streamlit exited with code 1 due to TypeError in python3.7/site-packages/google/protobuf/descriptor.py

[slowglow]

Thanks for the example of how to tie up FastAPI and streamlit in docker.

On two of my machines streamlit exited with code 1, as mentioned in the title.
The full trace is pasted below.
The solution I found was to upgrade the packages in streamlit/requirements.txt to their most recent versions:

-- original requirements.txt ---

streamlit==1.9.0 
requests==2.24.0
requests-toolbelt==0.9.1

-- modified requirements.txt ---

streamlit==1.10.0 
requests==2.28.1
requests-toolbelt==0.9.1

--- Screen output---

streamlit    | If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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

streamlit    |  1. Downgrade the protobuf package to 3.20.x or lower.
streamlit    |  2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
