Ah, cool, so someone else wrote this script to enable LCD display with OSPi. Judging from the error message, the issue is because in firmware 2.1.9, some json variable names have changed. For example, ‘urs’ is no longer there because it’s replaced by ‘sn1t’: ‘urs’ is the old variable name for sensor, but since the firmware now supports two sensors (sensor 1 and sensor 2) it has been replaced by new variable names. At the moment, either you can roll back to firmware 2.1.8 so the script still works, or you or the github owner can modify the script to make it compatible with firmware 2.1.9.
