Spring Boot Error when redirecting to html-file

Question

I always get a "NoSuchMethodError" in my Spring Boot application when I try to redirect to a html-file and I don't understand where this is coming from. Hope someone can help.

Background: An external server is sending some information to my server by calling a method via url /resolce. This method processed the information and shall deliver the information to a html-file via redirecting. The processing of the information works fine, but when it comes to the redirect I get an NoSuchMethodError. I thought the template engine can't find the view, but the configuration seems fine.

Here is the stacktrace:

The method:

@PostMapping ( "response" )
public ModelAndView postResponse ( ...,  UriComponentsBuilder ucb, HttpServletRequest request ) {
byte [ ] samlResponseAsBytes = DatatypeConverter.parseBase64Binary ( samlResponse );
...
return new ModelAndView ( "redirect:" + ucb.path ( "/delivery" ).build ( ).toString ( ) );
}

Application.properties

...
spring.thymeleaf.prefix = classpath:views/
spring.thymeleaf.suffix = .html
spring.thymeleaf.check-template-location = true
spring.thymeleaf.cache = false
spring.resources.static-locations = classpath:resources/
spring.resources.cache.period = 0

I've tried several locations for the delivery.html but as it is configured it should be under resources/views.

I can upload more informations, if neccessary.

Can someone help me please?
