I have enabled the telemetry module on the node to share temperature, humidity, pressure, and AQI.
Looks like the telemetry packets rise the exception:

You enabled the telemetry on a firmware config and this happened?!
Or you used this scrip?

I have enabled the telemetry on a firmware config.
API/Firmware bug possibly
What rev of code and node is it on? Rak? Wonder if it's a resource issue
I run current master on LilyGo T3-S3 v1.2 with firmware v2.7.5.
I can't replicate it on a tbeam
You sure it wasn't set while the bot was running? The node rebooted?
I can't replicate it now too. I will get back as soon as I get more info. Thank you!
