Description

After an update today (2025-11-06) from an old (at least a year since update) docker installation of appsmith, self hosted, An entry to the top level of the user interface gives an error popup saying "cannot read properties of undefined, reading 'brandColors'". The user interface then displays nothing under workspaces. There is a workaround to randomly click in the empty area, which eventually selects and loads the one and only workspace I have. As I am not a business user, I have no means to specify the brandColors.

Steps To Reproduce

Go to my application url Observe after a pause error popup at top of screen saying "cannot read properties of undefined, reading 'brandColors'"

Doesn't reproduce once the page has been loaded successfully Hard to catch with a snapshot because the popup doesn't stay there long enough
