Hi All,
I think I found a bug in Keycloak-x ftl template loading. Posting here to see if anyone is seeing the same behavior. This is a description of an extension that works fine in Keycloak.
- Place an .ftl template in the
src/main/resorces/theme-resources/templates/dir of any extension - Create an Authenticator or custom REST endpoint that serves the template, like:
...
return session.getProvider(LoginFormsProvider.class).createForm("foo.ftl");
}
...
- Deploy the extension to the
providers/dir of Keycloak-x (standard distribution or docker) - Get the following error, where the template cannot be found:
