API HTTP server errors with Azure AD B2C

Have a read of this post first.
Notice how a managed HTTP 409 API error is displayed on the user’s screen.
But what happens if the API returns a HTTP server error?
You can configure HTTP errors in Beeceptor.

Returning an HTTP 403 error (Forbidden) displays:

Returning an HTTP 500 error (Internal Server Error) displays:

Returning an HTTP 501 error (Not implemented) displays:

And so on.
You can customise these errors to some extent.
All good!
