This is my current project architecture:

.
./pom.xml
./src
./src/main
./src/main/resources
./src/main/resources/templates
./src/main/resources/templates/otp.ftl
./src/main/resources/templates/phone.ftl
./src/main/resources/META-INF
./src/main/resources/META-INF/services
./src/main/resources/META-INF/services/org.keycloak.authentication.AuthenticatorFactory
./src/main/java
./src/main/java/phone_otp
./src/main/java/phone_otp/AuthFactory.java
./src/main/java/phone_otp/Auth.java

And this is the part of my Auth.java that tries to load the phone.ftl:

    @Override
    public void authenticate(AuthenticationFlowContext context) {
        String phone = (String) context.getSession().getAttribute("phone");
        String errorMessage = (String) context.getSession().getAttribute("phoneError");

        LoginFormsProvider form = context.form();
        form.setAttribute("phone", phone);
        form.setAttribute("errorMessage", errorMessage);

        Response challengeResponse = form.createForm("phone.ftl");
        context.challenge(challengeResponse);
    }

And I get this error:

2025-10-11 14:09:11,288 DEBUG [org.keycloak.authentication.DefaultAuthenticationFlow] (executor-thread-5) invoke authenticator.authenticate: phone-otp-authenticator

	at org.keycloak.forms.login.freemarker.FreeMarkerLoginFormsProvider.processTemplate(FreeMarkerLoginFormsProvider.java:611)

And I use (jar-tools)[https://jar.tools/jar-viewer] to make sure that both phone.ftl and otp.ftl are in the templates directory.

What should I do?

Afaik, the template folder should be:
./src/main/resources/*theme-resources/*templates
