TTN/TTI had been updated to be the same as all other integrations at TagoIO.

That means that the variable “ttn_payload” will not be available in the payload global variable in the parsers anymore.
I do suggest that if you are using this variable, that you change to the proper parser format, as in the snippet “Parse example for LoRaWAN”

If you still need to access the ttn_payload for some reason, it is still available in the global variable “raw_payload” as specified in TagoIO documentation Context & global variables - TagoIO

Here is a code example:

const ttn_payload = raw_payload.find((data) => data.variable === "ttn_payload");

The change that moves ttn_payload, and similar variable name from the payload, to the raw_payload was applied 2 months ago. But only comes to TTN recently.
