title: THYMELEAF with Post Request : Error during execution of processor 'org.thymeleaf.spring5.processor.SpringInputGeneralFieldTagProcessor'
body: <p>I seem to have an error in my Spring Boot &amp; Thymeleaf Code for a simple Post-Request, but I just can't find it. I tried to reduce the case to the minimum but the error remains.
  Thank you for any helping hint!</p>
