Describe the bug

Chrome shows an error in the console for a text response for a js file.

The web server is sending a 500 text/plain message w/ Internal error as a response to a javascript include -- and the web browser is pissed that the script it requested did not result in a javascript file:

To Reproduce

Visit the login page when credentials (github dex oauth?) have expired and open browser web tools

Expected behavior

Serve a JavaScript file with the error inline in some form that doesn't result in errors from the browser.

Possibly:

/* Internal Error */

I am getting the same error, any workaround?

The code is here: https://github.com/argoproj/argo-cd/blob/b6cfe676f3ff9f73c71a0d6256c1bc14cd9c12ed/server/server.go#L1022-L1024

I suspect that you could "work around" this by adding some extension content.
