Describe the bug
Hello,

We spotted that there is a regression in the error handling in Rancher dashboard settings page.
Indeed, we have a webhook preventing customers to modify some critical settings (not all).
In v2.9.7 when the webhook returned an error, the error was display in an error banner:

But in version 2.10.1, the error is never displayed. Only the save button becomes red:

To Reproduce

• Install a webhook in Rancher namespace preventing settings modifications
• Modify a setting

Result

Expected Result
The error message is displayed in a red banner in the top of the page

Screenshots
See in text

Additional context
It relates to issue #9183 but it's a bit different because in our case, it worked in previous Rancher minor version (2.9) while it never worked on the driver page side.

Thanks,
Best Regards,
Thomas

The 2 issues are completely different. This one is related to the architecture changes in the major JS framework update.

I cannot generate a network response different from 200 when I use any type of value, which makes me think there's no validation at all from the server side.
Could you please point out a case and the response in the payload of the request in the network panel?

Sorry I re-read the issue description
