Deployed app not working

[Mayhem50]

I have migrated my application from firebase-element to polymerfire. Everything works fine until I deploy the app.
After, on local or on web many errors appear.
On web, errors are : Uncaught NotSupportedError, Uncaught TypeError: Polymer.Base._getExtendedPrototype is not a function, etc
After deploying, on local, it seams that it's an iframe that points to mywebsite.firebaseapp.com/__/auth is corrupted. Errors are same.
The workarround I find is to have a project for auth and database and deploy on other project. It resolves only auth corruption.

After long search I thinl the problem comes from polymer build process

I'm having the same problem, thanks for sharing your workarround.

I'm usign polymer-cli for building, @Mayhem50 are you?

Very similar issues here.
In my case mywebsite.firebaseapp.com/__/auth iframe doubles or triples every request.

example:
https://project-3846386819515834955.firebaseapp.com/

@mgibas I'm not seeing any errors when I open your site -- did you work out the problem?

I'm also hitting this issue, the suggested rewrite is causing requests to /__/auth and similar to return the contents of index.html

Are you configuring your auth-domain on firebase-app correctly? If you're pointing it at a firebaseapp.com domain there shouldn't be an issue here...

Yes same here and I've correctly configured my auth-domain both in the Firebase console and in my firebase-app but I still have the issue.
The only way to have the auth working is with the workaround given by @Mayhem50

I'm also using the polymer-cli for building my project, could this issue come from this ?
Here is my project to let you try auth.

@mbleigh yeah, I had to deploy a fix - sorry for that.
It seams to be a polymer-cli issue cause I switched to gulp (configuration from PSK) and all issues went away.

@cdata any ideas on what this might be?

[mshockwave]

I use Polymer CLI and encountered the same problem

[mshockwave]

I use @Mayhem50 's solution and it works. I delete every rewrite rules in firebase.json but the problem is still exist, so perhaps the polymer build tool add some additional rewriting / forwarding rules?
I would like to forward this thread to issues of polymer-cli repo.
