FTL Error: Failed at: #if !object[key]??

Hi, first thanks for your great work at keycloakify! :)

After upgrading our keycloak from 21.1.1 to 24.0.1, we get the following error:

2024-04-11 14:48:11,045 ERROR [freemarker.runtime] (executor-thread-3) Error executing FreeMarker template part in the #attempt block: freemarker.core._TemplateModelException: An error has occurred when reading existing sub-variable "attemptedUsername"; see cause exception! The type of 

the containing value was: extended_hash+string (org.keycloak.forms.login.freemarker.model.AuthenticationContextBean wrapped into f.e.b.StringModel)

I attached the referenced ft file: register-user-profile.ftl.txt.

I also found some other issues from the past that referenced similar errors, maybe this can help solving?

• Error when reading loginAction in logout-confirm.ftl template #391
• Using keycloak version 18 yields TemplateModelException #91

Thanks and let me know if I can help with more infos!

Hello @lokmeinmatz,

Thank you for the kind words.

I am actively working on updating the templates for Keycloak 24 and will provide a migration guide.

If you cannot wait, you may undertake the update on your own. It's important to know that register-user-profile.ftl no longer exists in Keycloak 24. Instead, register.ftl should be used, which now incorporates the user profile feature previously in beta.
