  • When all timestamp values in a time dimension column are NULL, min() and max() return NULL, and the dashboard showed "This may be due to access permissions" — misleading since the user has data
  • In Rill Developer (without mock user): show a message hinting at NULL timestamps / empty data source, since there are no access policies
  • In Cloud or Developer with mock user active: mention data source configuration or access permissions

Developed in collaboration with Claude Code

When all timestamp values in a time dimension column are NULL, the
dashboard showed a misleading "access permissions" error. Show
context-appropriate messages: in Developer, hint at NULL timestamps;
in Cloud (or with mock user), mention access permissions.
