Steps to reproduce

• Have at least one dataset record with icon_info set to null or missing icon fields.
• Sign in to the console.
• Open the Studio apps page at /apps.
• Wait for the shared header dataset navigation to load the dataset list.

Observed browser runtime error:

TypeError: Cannot read properties of null (reading 'icon')

The failing path is the shared dataset navigation, which reads dataset icon fields while rendering navigation items.

✔️ Expected Behavior

• The apps page renders normally.
• Datasets with missing icon metadata use a default dataset icon.

❌ Actual Behavior

• The page falls back to the generic error screen:

This page couldn’t load
Reload to try again, or go back.

• The crash happens before the user can interact with the apps list, even though the apps API request succeeds.
