spring restdocs - Rest docs use custom Snippet class is ignored

Question

I want to include a custom Snippet class of mine and therefor I followed the docs ( I use junit 5 ).

@BeforeEach()
    public void test(WebApplicationContext webApplicationContext, RestDocumentationContextProvider restDocumentationContextProvider){
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
                .apply(documentationConfiguration(restDocumentationContextProvider).snippets()
                        .withDefaults(curlRequest())).build();
    }

This test fails as all my Mocks ( Mockito ) are null during the test.

In general I wanted to use my custom implementation:

public class CustomHttpRequest extends HttpRequestSnippet {


    public CustomHttpRequest(Map<String, Object> attributes) {
        super(attributes);
    }

    @Override
    protected Map<String, Object> createModel(Operation operation) {
        Map<String, Object> model = super.createModel(operation);
        model.put("custom-path", removeQueryStringIfPresent(extractUrlTemplate(operation)));
        return model;
    }

    private String removeQueryStringIfPresent(String urlTemplate) {
        int index = urlTemplate.indexOf('?');
        if (index == -1) {
            return urlTemplate;
        }
        return urlTemplate.substring(0, index);
    }

    private String extractUrlTemplate(Operation operation) {
        String urlTemplate = (String) operation.getAttributes()
                .get(RestDocumentationGenerator.ATTRIBUTE_NAME_URL_TEMPLATE);
        Assert.notNull(urlTemplate, "urlTemplate not found. If you are using MockMvc did "
                + "you use RestDocumentationRequestBuilders to build the request?");
        return urlTemplate;
    }
}

and I adapted to:

 @BeforeEach()
    public void test(WebApplicationContext webApplicationContext, RestDocumentationContextProvider restDocumentationContextProvider){
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
                .apply(documentationConfiguration(restDocumentationContextProvider).snippets()
                        .withAdditionalDefaults(new CustomHttpRequest(null))).build();
    }

But still all my Mockito when... then.. definition are causing a Nullpointer exception.

e.g.

 @MockBean
    private AccountService accountService;

when(accountService.getAccountById(anyString())).thenReturn(account);

What is the correct way to include my custom class to the other existing snippets? Do I have to provide a .snippet file also that is will be created? And why does the snippet from the docs cause this error?
