Keycloak 19 doesn't load theme-resources

[peyman1372]

Hi, I'm getting this error with Keycloak 19, Keycloak 18 works fine

2022-08-08 13:00:10,092 ERROR [org.keycloak.forms.login.freemarker.FreeMarkerLoginFormsProvider] (executor-thread-19) Failed to process template: org.keycloak.theme.FreeMarkerException: Failed to process template login-sms.ftl at org.keycloak.theme.FreeMarkerUtil.processTemplate(FreeMarkerUtil.java:71) at org.keycloak.forms.login.freemarker.FreeMarkerLoginFormsProvider.processTemplate(FreeMarkerLoginFormsProvider.java:524) at org.keycloak.forms.login.freemarker.FreeMarkerLoginFormsProvider.createForm(FreeMarkerLoginFormsProvider.java:326) at dasniko.keycloak.authenticator.SmsAuthenticator.authenticate(SmsAuthenticator.java:69) at org.keycloak.authentication.DefaultAuthenticationFlow.processSingleFlowExecutionModel(DefaultAuthenticationFlow.java:446) at org.keycloak.authentication.DefaultAuthenticationFlow.processFlow(DefaultAuthenticationFlow.java:250) at org.keycloak.authentication.DefaultAuthenticationFlow.processSingleFlowExecutionModel(DefaultAuthenticationFlow.java:381) at org.keycloak.authentication.DefaultAuthenticationFlow.continueAuthenticationAfterSuccessfulAction(DefaultAuthenticationFlow.java:18

Keycloak 19 can't load any data from "theme-resources" folder, and the error happens in SmsAuthenticator class when it starts loading data from the folder.

Yes, there's something what crashes.
Due to lack of time I didn't have time yet to investigate and fix.

[dasniko]

This seems to be related to Keycloak itself, not necessarily to my extension. Maybe a regression bug.
I'm further investigating this.

[peyman1372]

Yes! I couldn't figure out the problem, though, I rolled back to Keyckloak 18, and it works fine!

There should be a fix in the next release (targeted for 19.0.2):
keycloak/keycloak#13825
keycloak/keycloak#13401

Updating to 19.0.2 seems to give some other issues tho, i took the project as is and just bumped the keycloak version (also had to do the spi-bom) and when you try and configure the sms step it throws an error as its trying to read a property on an undefined object.

I got the same error using keycloak 18.0.0 and spring boot 2.6.7. The thing is freemarker cannot find target template in resource folder and I don't know how to force it to look at the 'theme-resources' folder.
