Error, unable to make changes to Identity external providers

When attempting to make changes to Identity external providers, an error is raised:

A fatal rendering error has occurred

While your data is safe, the following JavaScript error caused the Netlify UI to crash:

u.get is not a function

This occurs whether attempting to remove a provider or edit an existing one. Adding additional providers does work.

I have observed this issue for at least two days now.

Browser console shows the following error information:

monitoring.vendor.bundle.js:1:98822
TypeError: u.get is not a function
    vx https://app.netlify.com/app.bundle.js:343

    React 5
    __trace__ https://app.netlify.com/monitoring.vendor.bundle.js:1

Additionally, there is a CORS error for netlify.bugsnag.com that may be preventing Netlify from observing these errors:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://notify.bugsnag.com/. (Reason: CORS request did not succeed). Status code: (null).

and a failed POST request to that URL is visible in the network tab.

Please refer to: External OAuth provers settings: fatal rendering error

That’s disappointing. One would think that the feature would at least be labeled as “deprecated” or even “broken” but preferably just disabled outright. Thanks.
