Payload formatters error TTN V3

i have an error message with ttn console v3 with the payload formatters.
I use [CubeCell Capsule Solar Sensor] with CCS811B sensor
I used the file given on github at this address: CubeCell_Getting_Started/ttn-decode.js at master · wasn-eu/CubeCell_Getting_Started · GitHub
can you help me?
thank you in advance.

Are you using the Firmware out of That github repository or have you flashed the Capsul with the wasn configurator?

Can you show the serial Output of the Capsul from the start to sending?

I found the solution !
what a sucker I am!
