Hi, dear friends.
I’m new to n8n, just starting out. It’s a really cool tool. I was working on a project and ran into a problem. The node keeps throwing an error, screenshots attached. I’ve done the standard things, like changing the API and address, and asked questions in GPT, DeepSpeak, and Gemini, but still no luck. If you know how to solve this, please help.
Benjamin, hello.
Thank you very much for your attention. Error in node МОЗГ 1:
Error Message: Authorization failed - please check your credentials. Missing Authentication header.
Node Name:МОЗГ 1 (it’s a sub-node, likely an HTTP Request or an AI Agent node).
n8n Version: 2.13.3 (Cloud)
It seems like the authentication header is not being sent correctly. I have already double-checked my credentials in the credentials section, but the error persists.
hello @Kuat_Ziyadanov
I see that your OpenAI base URL leads to the open router. Use the credential and a chat model from the Open Router then
Benjamin, thank you very much, changing it helped
Руддщ, thanks for the tip, I changed it.
