createAuthUri problem on login

[okandeb]

hello all,
when i try to login get

INVALID_CONTINUE_URI : Invalid parameter value for redirect_uri: fragment not allowed.

with 400 error code on ios. this is the request payload

{"identifier":"*****@gmail.com","continueUri":"http://localhost:8080/Users/okanseremet/Library/Developer/CoreSimulator/Devices/0976F085-0569-488D-8440-403F52BD13C5/data/Containers/Bundle/Application/A96557FB-A081-47E6-AFB4-BC8A097D14B4/MaxiLoyal.app/www/index.html#/welcome"}

but it should be like this. Otherwise it's not working.

{"identifier":"*****@gmail.com","continueUri":"http://localhost:8080"}

i tried to downgrade node version from 10.1 to 8.11.2 but not working

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Are you calling this with fetchProvidersForEmail or fetchSignInMethodsForEmail?

[okandeb]

Yes. using fetchProvidersForEmail method. Shouldn't I?

Edit: You are right. When i remove fetchProvidersForEmail method sign in flow works properly. But i have to use the method. Is there any way to check providers for email without using this method or any workaround?
Edit 2: I also tried fetchSignInMethodsForEmail but didn't work.

[bojeil-google]

I think it may be a bug in our backend code. This endpoint is also used for OAuth flows and redirect URIs are not supposed to have fragments per spec. It shouldn't be an issue for fetchProvidersForEmail or fetchSignInMethodsForEmail. Our team is investigating a fix.

[bojeil-google]

You can also file a support ticket via official channels to track the progress.
