I think that the request body is malformed @needtheanswers. You cannot put an array into multipart/form-data (unless Toddle sprinkles some magic on top that I am not aware of). The tags has to be tags[] (see screenshot). Usually in form-data, you would have multiple lines with tag[], but as this is an object in Toddle, you can only have one. This might be a Toddle limitation. I see two options:
1. Create the form-data yourself in a custom formula
2. Upload the image first and then add the tags to it.
Any better ideas, @Lucas G?
