Hello, good morning.

I'm receiving data from my MQTT broker, but when sending null data, I get this error:

The JSON value for 'route/company/destination/station/61/host-serial-number-uri' is null.

I'm using the payload with the MQTT engine. The problem is that I don't own the sender, so I can't prevent it from being null, and there are a large number of tags that could be affected by this.

Has anyone solved this?
