Hey been getting error lately while editing apps, and navigating from one app to another (e.g. in breadcrumbs, buttons or links). Haven't changed anything relating to navigation.
Any ideas?
Hello @hansontools,
The "Missing page UUID" error in Retool usually appears when navigating between pages in an app especially after updates, refactoring, or working across multiple branches.
This often happens because Retool can't locate the page's unique identifier (UUID), which may be missing, outdated, or corrupted especially in source control workflows.
-
Double-check UUID references: Ensure all navigation (breadcrumbs, buttons, utils.openApp(), etc.) points to valid and current UUIDs.
-
Update old app/page names or links if they were renamed or removed.
-
Export and Re-import the app: In the app editor, go to settings → export as JSON → create a new app → import JSON.
Still stuck? Reach out to Retool support they can help debug UUID issues on the backend.
I tried these steps in my app (see screenshots for reference):

I have the same problem. I have created a module for production where I am sharing the same menu through all the apps, and when I change between apps in edit mode, the same error appears.
I have checked all of the app targets, and everything seems correct.
