GPTs action not using provided URL, instead creates an internal plugin

I am trying to create an action for my GPT, it uses a simple get API to retrieve a string response.

I get no response, on further talking to the GPT, it states the following:

When prompting to retrieve a string response, i used the internal api-Name-used-by-me plugin specifically designed for this task, not a direct URL

Any Idea ???

Here is the screenshot of the conversation.
GPT is Untitled.

The last 2 responses from the GPT are were it states the above facts.

Also note, in 3rd last response, GPT gives no rsponse, it is Blank for some reason

Just publish the GPT then check, it works normally then
