Keycloak social login key

I’ve configured our keycloak server as a social login key and it seems to work ok until I get redirected back to erpnext after the user has been verified. ERPnext spits out this error:

Traceback (most recent call last):

How do I even go about debugging this? Any direction would help. I am using Keycloak v11.0 and ERPNext v12.11.2 on Ubuntu 18.04.

Thanks,

This is my working Keycloak integration configuration.

Ohhh, ok I had scope set to “openid email profile”. I will try that later.

BTW, did you have to pre-create the user accounts so the login names match? Or does erpnext create a user on the fly?

ERPNext will create user if it doesn’t exist.

User will be website user without any access to desk.
Set the default role in portal settings

If user is already created and appropriate roles are assigned, it will sign in as that user.

Ok, well I got a little further but still no luck. I didn’t get an error message after keycloak authenticates, all I got was a page that displayed this:

{}

If you got it working then at least I know it is possible somehow. I’ll try building a brand new fresh VM with erpnext. If that doesn’t work, then there must be something wrong with my keycloak configuration.

Well, I officially have no idea how @lapphan got keycloak integration to work. I installed a brand new version of erpnext from scratch on ubuntu 20.04 and used the exact same settings and I still get the exact same results.

Something is definitely missing here and I’m not sure where to even start to debug this.

Hello,
I have the same issue here. I put the same configuration of keycloak authentification provider. When I try to connect via social networks by choosing the new keycloak configuration, the connection window switches to the keycloak authentication server. after entering the user/password, the callback URL is invoked but rather than I connect on ERPNext, I get the message :
{}
displayed on the browser. any idea on this issue ?
Thanks in advance
