Spreadsheet component and issues with lists from ReadRange-GotRangeData

[alelalelale]

I'm using the Spreadsheet component to read a placing with empty row

I'm reading the range B2:E11 with ReadRange but when I get the list from GotRangeData, the app gives me this error:

Can you tell me how to solve this issue?
Thanks

You have empty rows in your range result.

Test for empty list before attempting to extract cells.
