For upload, I am using the command provided directly in RASA X UI.

Anyone knows what cause this behaviour?

what’s the url of rasa-x server :? it not contain /api/ after domain name,

examle: http://my-rasa-x.com/project/…api_token=sadasd

its must be : http://my-rasa-x.com/api/project/…api_token=sadasd
