Unable to add a cover image to an Odoo blog post

Hello,

I can’t add a cover image with Odoo’s “Make an api call” module.

I’d like to create an article with title, slug, content and then assign an image.

Currently, I have a base64 image that I’m trying to import into Odoo, but the image won’t add to the media…

This is problematic.

Does anyone have a solution?

Thanks a lot.

Here are some images of the configurations:
