the response content is not what you are expecting...
therefore the for each in list loop will run into that runtime error

before using the for each in list loop, check if global_json_listar is a list...
you can find that block in the List drawer...

Taifun, thanks for the massive help! God bless you, how can I take this test?

if is a list global_json_listar
then do your preccessing
else display a nice error message
