Reports of user getting the badtoken API error. This was traced back by the user to the user's session having expired during the steps of the upload.
The wizard (and much of our JS/API/UI btw) does not really handle expired sessions nicely, probably an area where we need to improve. I believe we have an 'assert' for this on the API nowadays ? Perhaps it needs to be used by the UW api calls.
