I cant resubmit my model to deep racer

Hello, "Couldn't retrieve your latest submission for this leaderboard" usually means one of two things: either you got logged out and the API calls are no longer working or you lost permissions to access the page. If this is a public race and you are confident that the admin could not remove your access, refresh the page - it usually then takes me to the login page. Alternatively, when using SSO portal, I've seen the AWS console confused about what I was and wasn't permitted to do after switching between my roles. In such case logging out and back in usually was enough to clean up and align my role and permissions.
