BUI console records are stuck on loading screen
Answer ID 13155   |   Last Review Date 06/30/2026

Why is the BUI console showing a loading circle and getting stuck?

Environment:

All supported versions

Issue:

When using Browser UI (BUI) in a Chromium-based browser such as Google Chrome or Microsoft Edge, you may experience issues when opening or updating records. When this occurs, the workspace displays a loading circle on a blank background and never finishes loading.

Resolution:

Customers experiencing BUI loading issues should first generate browser console logs (see "How do I generate a Console log in Chrome or Firefox?") and check for the following warning:

[Violation] Permissions policy violation: unload is not allowed in this document.

If this warning is present, the issue is likely related to the Chrome or Microsoft Edge browser deprecation of the unload event.

Oracle Browser UI (BUI) has been updated to address this browser feature deprecation. The fix is available beginning with BUI version 3.26.07.17-b0002.

If the customer is running BUI version 3.26.07.17-b0002 or later, this issue should already be addressed. If the issue persists, verify that any deployed BUI extensions are also compatible with the browser changes.

If your team is unsure whether any BUI extensions utilize the unload event, perform the following test:

1. Log in using an account/profile with access removed for all BUI extensions.
2. This setting is available on the profile's "Agent Browser UI Extensions" tab.
3. Attempt to reproduce the issue.
4. If the workspace loads successfully, re-enable the extensions one at a time until the issue reoccurs to identify the extension responsible.

If upgrading to the required BUI version is not currently possible, the following temporary workaround may be used:

1. Open the appropriate browser flag page:
  - Google Chrome: chrome://flags/#deprecate-unload
  - Microsoft Edge: edge://flags/#deprecate-unload
2. Set "Deprecate unload" to Disabled.
3. Restart the browser.
4. Verify whether the workspace loads correctly.

Note: This workaround should be used only as a temporary measure. Upgrading to BUI version 3.26.07.17-b0002 or later is the recommended long-term solution.

Cause

This issue is related to the announced deprecation of support for the unload event in Chromium-based browsers. Google Chrome and Microsoft Edge are progressively removing support for this event, and browser updates may block or restrict its use.

If the browser console logs contain the following warning:

[Violation] Permissions policy violation: unload is not allowed in this document.

the issue is likely related to the browser's unload event deprecation. Browser UI has been updated to address this behavior beginning with BUI version 3.26.07.17-b0002. Custom BUI extensions that continue to rely on the deprecated unload event may also require updates to remain compatible with current Chromium-based browsers.
