Describe the problem/error/question
Hello! So I have an error with adding my ChatGPT to my agent; it says that I’m out of my quota even though I have a plus account and am no where near reaching it.I followed the advice on another part of the forum where someone else had posted about the issue in Jan/Feb (i.e I put in a new API key) but its still not working and in fact it almost looks like it fully freezes when I try to input anything in the chat. I’m a total newbie here - really just working myself some of the n8n tutorials so this is a very basic set up, but not sure how to navigate this and would appreciate any help I can get. If anyone has other ideas besides a new API key, I’m all ears!
What is the error message (if any)?
