Exception: Smart contract is not Jetton or NFT
It seems that the exception is not caught properly, which forces the gunicorn worker to exit. The worker on the gunicorn server may serve many requests at the same time, and the forced exit causes EOF or connection reset by peer error on the client sending the requests.
Below is the command and some envs used by the ton-http-api container.
command: -c "gunicorn -k uvicorn.workers.UvicornWorker -w 32 --bind 0.0.0.0:8080 pyTON.main:app"
environment:
- TON_API_GET_METHODS_ENABLED=1
