Creating a new GPT with action

[shimon.m]

I have a question regrading the development of a new GPT, adding instructions is clear but when I try to create an action with functions, the model is not interacting with them and I’m getting this error “Error talking to…” even though the endpoint is active and I’m getting a response from postman

I read in the documentation that " To create an Action, you can define an OpenAPI specification similarly to that of a plugin with a few changes listed below. If you have a plugin today, creating a GPT with an action should only take a few minutes.

You can start by [creating a GPT in the ChatGPT UI and then connect it to your existing plugin OpenAPI reference("

so this means that I can only use actions from a verified plugin?

Have same issue - in my case the problem was parameter was sometimes too long to be sent via query string.
