Connection with Open AI message a model

Hi, I am new to n8n and trying to build some basic agents but while I am trying to connect with the Open AI message a model, I am getting an error saying you are sending too many requests at a time. Tried with gemini to again the same error. Can someone help me resolve this issue plz?

I believe you hit the rate limit

But how to overcome this problem?

What is the rate limit of your plan?

see now I am not able to select a model form the list

You can just type in your model name

That is also not allowed, is there any online assistance provided on a call by any chance?

what is your n8n version?

It’s a cloud version with 15 days free trial

There should be a version number

Can you try to downgrade to 2.17.x ?

Ok let me try that

I can select the model after the downgrade, thanks a lot!

Welcome, please mark my reply as solution. Thank you!

While executing getting this error

I believe this is the key

Does that mean I need to buy a plan or change the chat model?

Possibly, has the credit in your Open API key been depleted?

Let me check
