I strongly believe that you have not added blocks properly the gsheet items into the global lists. See global artist is showing nothing it means nothing is printed
When web1 got text
Set global Google response to list from CSV table text to get response content
In the web got text itself you have added element to global artist but here it is telling empty list. So meanwhile you have re created this variable to empty list. Pls check up it
Yes I have created a variable with empty list because here you will see that I have also make a variable with empty list but here it is working but for artist when i create a list of empty list then it was not working why this happen??
Based on the above blocks it seems, web index 1 is not executing. If it executes then you will get values in global artist. Make sure you have set set global web index to 1 while the web url executes first time
The problem may be you did get response from gsheet (your error clearly says). So Please check the web response when you set web index to 1 or check the web url also in the same place…
