Read Data from Table

[AlexD]

Hello.
I saw this post and I had to try this myself, but it did not work. 

This is my script that I have copied from here:

Code:

alarms = data['smoke_co_alarms']['RTMTKxsQTCxzVcsy.................s']

key, alarms = next(data['smoke_co_alarms'])
co_alarm_ok = alarms['co_alarm_state'] == 'ok'
grp.update('4/4/3', co_alarm_ok, dt.bool)

smoke_alarm_ok = alarms['smoke_alarm_state'] == 'ok'
grp.update('4/4/4', smoke_alarm_ok, dt.bool)

battery_health_ok = alarms['battery_health'] == 'ok'
grp.update('4/4/5', battery_health_ok, dt.bool)

And this is the error: 
"Nest Protect 11.10.2022 10:58:19
Resident script:1: attempt to index global 'data' (a nil value)
stack traceback:"


This is the API from google nest:
