Cannot use multi transactions?

I am trying to use Exposed with SpringBoot and MySQL. When I use two transaction s, First transaction is executed. But second transaction is ignored without errors. Can I use multi transactions?

example

This is based on a tutorial of Spting Boot. https://spring.io/guides/tutorials/spring-boot-kotlin/

@RestController
@RequestMapping("/api/article")
class ArticleController() {

    @GetMapping("/test")
    fun test(): List<String> {
        transaction {
            User.insert {
                it[login] = "no1_" + java.lang.Math.random()
                it[firstname] = "one"
                it[lastname] = "one"
                it[description] = Date().toString()
            }
        }
        transaction {
            User.insert {
                it[login] = "no2_" + java.lang.Math.random()
                it[firstname] = "two"
                it[lastname] = "two"
                it[description] = Date().toString()
            }
        }
        return listOf<String>("test")
    }

mysql> select * from User;
+----+------------------------+-----------+----------+------------------------------+
| id | login                  | firstname | lastname | description                  |
+----+------------------------+-----------+----------+------------------------------+
| 17 | no1_0.9963653238062685 | one       | one      | Mon Mar 09 13:01:29 JST 2020 |
+----+------------------------+-----------+----------+------------------------------+

When I tried again, I got error java.sql.SQLTransientConnectionException: HikariPool-1 - Connection is not available, request timed out after 30001ms. . That looks waiting for transaction to be committed.
