Issue with json expression [BUG]

[andonoc]

Describe the issue I encountered a issue, when i was running the 2.9-1 version. On the Telemetry tab the keys and values are shown as the JSON expression from the mqtt.json file but they are processed to the right places.

I reversed now to 2.8-1 and everything works as expected

I checked the Thingsboard-gateway version with this command: sudo apt install -s ./python3-thingsboard-gateway.deb

Yes, same problem to me.

Some values are displayed correctly, but others are not.
