I am trying to upload my game with the command butler push "C:\Users\JDOGG\OneDrive\Desktop\Games" jonathanhaile.itch.io/a-mind-game:win

I keep getting a itch.io API error (400): /wharf/builds: invalid target (bad user) 

I have no idea what I am doing wrong and could use some help!

Please check the troubleshooting tips on our butler guide here: https://itch.io/t/2872417/how-to-upload-your-game-or-project-to-itchio-with-butler

You wrote out the username section incorrectly in the push target. Do not put itch.io in it.
