为什么带有嵌入式H2的Spring Boot会抛出'org.h2.message.DbException‘错误？

spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver

@Repository
public interface UserRepository extends JpaRepository<User, Long> {
    @Query("SELECT u FROM User u WHERE u.name = ?1")
    User findByName(String name);
}

CREATE TABLE IF NOT EXISTS users (
    id BIGINT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    email VARCHAR(255) NOT NULL
);

spring.datasource.hikari.connection-init-sql=GRANT ALL PRIVILEGES TO sa;
