Hi. Why don’t you use OpenAI Node instead of HTTP Request Node?

I use the HTTP Request node for custom OpenAI API calls because it gives me full control.

If you work with binary files, I think this will solve your question.

Use the plain binary property name (e.g., data) in the “Input Data Field Name” field.

Do not use an expression that resolves to the binary data itself.

Ensure the binary data exists on the item before the HTTP Request node.

Do you try to send first the binary, and then you try to send some text consecutively?

Please provide the workflow, or image .
