How to access OIDC client information in Keycloak E-Mail templates? - keycloak

Question

I know how to access some variable information in Keycloak E-Mail templates. E.g.:
user.getUsername()
user.getEmail()
user.getFirstName()
user.getLastName()
But I need to access client specific variables. The Keycloak Java Code shows there is all information I need in the ClientModel Java Class: https://github.com/keycloak/keycloak/blob/main/server-spi/src/main/java/org/keycloak/models/ClientModel.java
client.getClientId()
client.getName()
client.getDescription()
client.getRootUrl()
client.getBaseUrl()
client.getAttribute(name)
And the client_id=account Query Parameter is also set on the page, where the password reset action is triggered:
https://example.com/auth/realms/my-realm/login-actions/reset-credentials?client_id=account&tab_id=bQiVx012SZg
The information is set on the client:
But the client varaible seems to be unset while the email template gets rendered.
# password-reset.ftl
# This does NOT work
${client.name}
# This does NOT work
${kcSanitize(msg("clientinfohtml",client.getName()))?no_esc}

Answer 1

Yep, client segment seems not accessible and give https://null !
But if you check availabilty of segment it is not empty!
<#if client?? && client['baseUrl']?? && client['baseUrl']?has_content>
<img height="100" src='${client["rootUrl"]}/${kcSanitize(msg("emailSignatureLogoUrl"))?no_esc}' style="max-width: 250px;">
<#else>
<img height="100" src='${kcSanitize(msg("emailSignatureLogoUrl"))?no_esc}' style="max-width: 250px;">
</#if>
This is the same result with client['rootUrl']
