API call is completely broken

Hi everyone,
I’m doing an API call for a repeatingGroup and it’s not something that I’m doing for the first time, I did a lot of similar calls through the whole project, but this specific one keeps giving me problems, since it gives me this screen every. single. time.

I don’t know what to do anymore because I reinitialized that call for like 5 times now, but still nothing happens.

P.S. There is no call named like that

Try to build another API to see if something is missing or broken.

@JohnMark I tried re-building it from scratch but nothing changed at all. I changed the whole approach and it seems to work but I still don’t know what happened, because I even tested it on Postman and it worked perfectly
