Hello, I’m on n8n Cloud and I can’t connect my OpenAI credential.

Error: config.headers.setContentType is not a function

My OpenAI API key is valid, credits are active, and Organization ID is empty. This looks like the known n8n 2.18/2.19 issue with OpenAI credentials / axios headers.

Can you update or patch my instance?
