[SDK-2139] Add errorPath configuration

[frederikprijck]

Provide a way to configure Auth0-Angular to redirect to a custom path when an error occurs as part of the login request.

• Needs more testing to verify the removal of setTimeout doesnt break anything.

Needs more testing to verify the removal of setTimeout doesnt break anything.

Is the PR ready to review in that case or should we hold off?

[frederikprijck]

It is ready for review in that sense that I would love some feedback on potential edge cases that we might know that would have required the setTimeout.

It looks like callback is working fine for me. But I want to make sure.

Marked as draft, to avoid merging. But would appreciate your feedback #84 (comment)

[frederikprijck]

Done some more testing, should be ready to go.

Thanks @frederikprijck! I haven't had a chance to actually test this, but it looks like it should solve #79.

[stevehobbsdev]

Looks good. Let's ensure the related issue is linked to the PR, or it is at least closed when the PR is merged.

Hi @frederikprijck - forgive me for not opening a new issue to ask this question, but do you think it would be possible to pass the error and error_description querystring params to the errorPath URL?

The reason I ask is that I am using an Auth0 rule that prevents users from signing up using Social providers (see: https://auth0.com/rules/disable-social-signup).

I can redirect them to the error URL using the changes in this PR but I cannot see a way to pass the error and error_description querystring params which means I cannot display the appropriate error message to the user, only a generic "something went wrong" kind of error message.

Thank you,
Chris

Hey @cmjacques ,

Before redirecting to the error path, we emit the error in the errorSubject$: https://github.com/auth0/auth0-angular/blob/master/projects/auth0-angular/src/lib/auth.service.ts#L130

You should be able to use the error$ observable to track the error information and show an appropriate error message anywhere, including on the error page.

Let me know if that doesn't help.

Thanks for the very fast reply @frederikprijck - I will give it a go now. Cheers!

Works like a charm. Thanks again @frederikprijck. All the best.
