Umbraco AI tree requests return 401 after session inactivity until page reload

[gonziii]

Which component is this issue related to?

Umbraco.AI (Core)

Which Umbraco AI version are you using? (Please write the exact version, example: 10.1.0)

1.10.0

Bug summary

Sometimes when clicking an item in the Umbraco AI tree, the content does not load. After performing a full browser refresh, the same action works as expected.

Additional notes

This issue is intermittent and difficult to reproduce consistently.
It seems related to session/token expiration after inactivity.

Specifics

• Clicking a node in the Umbraco AI tree occasionally results in no content being loaded.
• In the browser’s network panel, the request returns a 401 Unauthorized.
• Example: this occurs when loading providers in Connections.
• After refreshing the page, the request succeeds and the content loads correctly.

Steps to reproduce

1. Open the Umbraco AI section in the backoffice.
2. Leave the browser tab inactive for a while.
3. Return to the tab and click an item in the tree (e.g., Connections → Providers).
4. Observe that the request may return a 401 and no content is loaded.
5. Refresh the page and try again — it works.

Expected result / actual result

Clicking an item in the tree should consistently load the corresponding content without requiring a page refresh.

Dependencies

Umbraco 17.3.5

This is a CMS issue see umbraco/Umbraco-CMS#22647

We do have a temporary workaround coming out, but it really needs to be resolved at the CMS level
