Error script versions

I did some testing today by creating a VDS and then I made several changes. When I try to go back to previous version the error is thrown on the screen

For some reason it loses the reference of what was changed. I am using Dremio Cloud Free.

@a6santa When you say you went back to the previous version, did you click on the bubbles on the right side of the screen. That option is only to quickly view previous SQL and not roll back the VDS version
