Simulator returns the following error whilst trying to connect.

ERROR:root:CP1: received 1011 (internal error); then sent 1011 (internal error)

Gateway Container is showing the following Log output.

Exact same issue encountered.

Please try updating src/ocpp-gateway-container/requirements.txt to fix the version of the mqtt package to one that pre-dates the version increase of path-mqtt to v2.0.0; e.g.:

asyncio-mqtt==0.16.1

If that solves the problem we’ll update the same in the repo. Thx!

I've updated the src/ocpp-gateway-container/requirements.txt file:

boto3
websockets
asyncio-mqtt==0.16.1

And now get the following error in the Gateway Container logs:

Successfully set IOT certificates

ERROR:websockets.server:connection handler failed

It looks like asyncio-mqtt use paho-mqtt for mqtt client. paho-mqtt client latest version is 2.1.0 but they removed message_retry_set at version 2.0.0. https://github.com/eclipse/paho.mqtt.python/releases/tag/v2.0.0

So specify paho-mqtt version in src/ocpp-gateway-container/requirements.txt fixed this problem.

boto3
websockets
paho-mqtt==1.6.1
asyncio-mqtt
