Latest release I read this was removed, well it seems it wasnt.

The community member posted about an error they encountered after removing an environment variable, which required them to add it back to get the application working. The error message indicated that the NEXT_PUBLIC_VIEWER_URL environment variable was required. In the comments, another community member suggested that the original poster may have misread the variable name, as they had written VIEWER_URL_INTERNAL instead. The third comment acknowledged this, but the community member stated that they never had a VIEWER_URL_INTERNAL variable, and that NEXT_PUBLIC_VIEWER_URL was the closest to what they were looking for.
