Hi,
I have a database with the following columns...
id t_1 t_2 t_3 ... t_(n)
I have a function which queries t_1 based on a row id and the returned message.payload looks like this...
I am trying to get a function that detects if t_1 is null as per the below...
I'm sure my problem is in Line 2 but I am not sure how to drill down to the point where t_1 is null
Have also tried the switch node as my result is either null or not but feel my issue is kind of the same regardless, I have a syntax error.
Any ideas greatly appreciated
