The 400 Bad Request is coming from the server you are trying to upload to. This is saying the request from your Mendix application has been sent in an incorrect format.

In your Mendix app you can turn up the Log Level of the REST Consume log node to TRACE to see exactly what your application is sending and the response from the remote server. If you are working locally this will be in the console of Studio Pro. Hopefully you’ll see what is going wrong with the request in your logs now.

Good luck!
