If you have questions reach out
This is an error from OpenAI. Hence, you need to contact their support to get more insights. However, to get the right parameters, please try the playground tool. Once parameters are confirmed, implement them in the HTTP module to avoid this error.
@Nelson_Keating One option is to use Cloudconvert to reduce the file size. Though I can’t get the HTTP to work with an attached file so probably will abandon Integromat for n8n (which works). Which HTTP parms worked for you?
