I am working with WebTestClient in Spring Boot Reactive app. I use the UriBuilder to include a custom pagination range object written in Kotlin that I've got no visibility of. It works until the documentation point which give the message below:

java.lang.IllegalArgumentException: urlTemplate not found. If you are using MockMvc did you use RestDocumentationRequestBuilders to build the request?

My code generating this error looks like this:

@Test

void findAll_shouldSucceed() {

    webTestClient.get()

                 .uri(u -> u.path(API)

                            .queryParam("range", toRangeParam(DEFAULT_RANGE))

                            .build(ID))

                 .header(AUTHORIZATION, AUTHORIZATION_HEADER)

                 .exchange()

                 .expectStatus().isEqualTo(PARTIAL_CONTENT)

                 .expectHeader().contentType(APPLICATION_JSON_UTF8)

                 .expectBodyList(MyObject.class)

                 .consumeWith(t -> {

                     List<MyObject> incomes = t.getResponseBody();

                     assertThat(incomes).isNotEmpty();

                     incomes.forEach(i -> {

                         assertThat(i.getId()).isNotBlank();

                         assertThat(i.getRange()).isNotBlank();

                     });

                 })

                 .consumeWith(document(RETRIEVE,

                                       requestParameters(

                                               parameterWithName("range").description("number of results")),

                                       paginationResponseHeaderDesc(),

                                       requestHeaderFieldsDefaultGet(),

                                       idPathParamDesc(),

                                       incomesResponse(),

                                       dslContract()));

}

Can I use the UriBuilder or do I have to concat the requestParam? which looks like so GET /api/processes/TYM_309de2cdc94345f18/products?range=0-49

The problem line is at the requestParameters documentation part of the code. The method toRangeParam() converts the Kotlin custom range object from a @QueryMap Map<String, String> contentRange in a retrofitClient to its String representation. Changing it to use the original map format like so .queryParam("range", DEFAULT_RANGE.toQueryMap()) produces this error:

java.lang.IllegalArgumentException: Not enough variable values available to expand 'range=0-49'

Any help will be appreciated. Thanks!
