Google Sheet Retrive Data Number

Hi guys!
I have a problem with Google Sheet Block.
When I try to Retrieve Data using a number I get the error “Action Retrieve Data for integration Google Sheet failed undefined”

This is an example.
I have the variable CHECK set to 1.
I Increment it by 1 with Set Block and it become 2.

I Create Data and write 2 in “N” column.

I Retrieve Data with settings N = {CHECK}
Trying it in Test it give my the error above (and using Alexa too).

In the same way, if I try the Test Integration I get this error
Something went wrong. Please check your request

What’s the problem?
Am I doing something wrong?
