  <p>I can still use the built-in functions in Repository such as save(), findAll(),... but when I add and use some functions, for example &quot;existsByUsername&quot;, it has error:</p>
  <pre><code>11:53:26.562 [http-nio-8081-exec-1] WARN  o.s.d.n.c.Neo4jPersistenceExceptionTranslator - Don't know how to translate exception of type class org.neo4j.driver.exceptions.NoSuchRecordException
  </code></pre>
  <p>Then, I try to add query for function, it is still

  <p>Could you help me to determine this error and give me a solution? Thank you!\</p>
  <p><em>Updated:</em>
  I call API in Postman, I received this result while my DB has only 1 user:</p>
  <pre><code>{
      &quot;error&quot;: &quot;Records with more than one value cannot be converted without a mapper.; nested exception is java.lang.IllegalArgumentException: Records with more than one value cannot be converted without a mapper.&quot;
  }
  </code></pre>
