C4W3: Graded External Tool - Couldn't read data from file "payloads/request-body.json"

I am sending the request to the model but I’m getting the following error:

“Couldn’t read data from file “payloads/request-body.json”, this makes
Warning: an empty POST.”

The gateway_url looks fine to me

I’ve been stuck for some time… And I have no idea on how to fix it.

Hi! From the warning message, it seems it cannot find the payloads folder. Please make sure that the folder exists and you are executing the command from the parent directory of that folder. Hope this helps!
