I had sent the following email to you as a private message on June 20, did you receive it? I have now obscured the actual email address.
Hi,
Thanks for sending the detailed log. After looking at the token, it looks like there may be two user records using the same email id -<some email id>
We don't support two users having the same email address. It is possible the user you are logged into horizon workspace, failed provisioning to data, as it is a duplicate email. Hence, you are not able to access the COS.
Can you change the email address and re-provision? Or delete the other user?
