How to send files from File Uploader element in POST request

I have same issue. I am going to upload file to OpenAI using OpenAI file upload API.
I have file uploader element and button element. I call the API in Bubble click workflow. But it still give me error message.


I think it’s because OpenAI file upload endpoint only accept byte stream of the file. @Jici , could you help me? Thank you.

You didn’t activate “send file” checkbox in API Connector
