GPT custom "oops an error occurred" every time I try to use API requests

Hi, im dealing with some unexpected issues. im making a custom gpt with gmail api and one with google calndar api. in the first one EVERYTIME y try to use an api request the screen breaks and it shows “oops an error occurred” (it wont even let me log in with the oauth screen). with the calendar api i can log in and make GET requests but every other http verb generates the “stopped talking to” response.

It seems weird because they work differently. has this happened to anyone? any suggestions?

It is difficult to debug through GPT configuration. You can try asking for error messages but that will be painful. I suggest you first verify your API requests simulating the requests using postman or curl requests. Similar to testing OAuth GPT. And only when you have the whole flow tested then configure your GPT.
