Describe the problem/error/question

Getting this all of a sudden when using the Code node. I recently upgraded to 1.64.3.

What is the error message (if any)?

Hey @ManOnFire1978 , I have not encountered such an issue when trying AI code generation in my workspace on 1.64.3.

Here’s a workflow I used with the instruction “count unique users where user is composed of firstname and lastname”.

Make sure the previous node has data in the output connected to the Code’s input.

Perhaps AI could not understand your instructions.

So I turned on debug mode in Chrome, went to console and saw this -

“message”: “Something went wrong: This model’s maximum context length is 8192 tokens. However, your messages resulted in 8796 tokens. Please reduce the length of the messages.”

So I need to work to reduce the amount of items in the input for it work again.
