Hello @RafaelAugustoR,
Could please share your n8n version? You write it down “latest” but it is better to know the version number.
Here some other possible input for you:
-
Make sure you’re passing a properly formatted JSON object to the OpenAI node. Even small issues in the structure (e.g., undefined values, extra commas) can silently break execution.
-
Double-check the selected model (e.g., GPT-5 vs GPT-4) and keep prompt + response token length well below the model’s limit. Overflows can sometimes crash the node without clear errors
-
If you’re using the Memory tab in the OpenAI node, try disabling it. Some users have reported memory persistence causing crashes in loops.

Hi, @Gallo_AIA.
That’s the n8n version: 1.105.4
I’m using GPT-4.1, but when i use GPT-5-nano, i got the same problem.
Thank you for the support and sorry for my english.
@RafaelAugustoR try to update the n8n version to 1.06 version and retry.

@Gallo_AIA This issue persists in version 1.07. We have verified that the JSON output is correctly formatted. Could you please investigate the root cause?
