Traccar as "nil value"

[PolymorphedCust]

Hi

I tried making the Traccar location-script working, but ended up with an error log that stated:
User script:3: attempt to index global 'traccar' (a nil value)

I followed the instruction as much as I could ( Geolocalization with LM based on Traccar service | Logic Machine platform for KNX/EIB, EnOcean, Modbus, DALI, BacNet (openrb.com)) 

Furthermore, I'd like to try to make a script so that, when I leave "home", I get a message via Telegram. I do believe, when the traccar scripts are up and running, this might be fixed.

Hope you can help

Thanks in advance!
