Forgot username not working

[cheekian yap]

Hi,

cas version 6.2.6

Reset password is working fine for me but forgot username is not.

Here is my configuration:

cas.authn.pm.enabled=true

cas.authn.pm.reset.expirationMinutes=1

cas.authn.pm.reset.security-questions-enabled=false

cas.authn.pm.jdbc.user=xxx

cas.authn.pm.jdbc.password=xxx

cas.authn.pm.jdbc.driver-class=com.mysql.cj.jdbc.Driver

cas.authn.pm.jdbc.url=jdbc:mysql://127.0.0.1:3306/test

cas.authn.pm.jdbc.dialect=org.hibernate.dialect.MySQLDialect

cas.authn.pm.jdbc.password-encoder.type=DEFAULT

cas.authn.pm.jdbc.password-encoder.encoding-algorithm=SHA-256

cas.authn.pm.jdbc.sql-find-email=SELECT email FROM user_info WHERE name=?

cas.authn.pm.jdbc.sql-find-user=SELECT name FROM user_info WHERE email=?

cas.authn.pm.jdbc.sql-change-password=UPDATE user_info SET password=? WHERE name=?

cas.authn.pm.reset.mail.from=x...@gmail.com

cas.authn.pm.reset.mail.text=Reset your password with this link: %s

cas.authn.pm.reset.mail.subject=Test

spring.mail.host=smtp.mailgun.org

spring.mail.port=587

spring.mail.username=xxx

spring.mail.password=xxx

spring.mail.properties.mail.smtp.auth=true

spring.mail.properties.mail.smtp.starttls.enable=true

And the error log I got:

2020-12-26 14:19:07,635 WARN [org.apereo.cas.util.io.CommunicationsManager] - <Could not send email to [xxx] because either no from/to/subject/text is defined or email settings are not configured.>
