Cannot use bodyBase64 in response since #593

[sylvainlaurent]

Since #593 (v2.5.1) base64Body cannot be used in the response: the exception is (with 2.14.0):

java.lang.NullPointerException: The input is required.

it's OK with 2.5.0.

Can you share the code (or example code) and/or mapping that causes this exception?

Actually the problem occurs if I specify the ResponseTemplateTransformer globally:

public class TestWireMock593 {

    @Rule
    public WireMockRule wireMockRule = new WireMockRule(wireMockConfig().dynamicPort().extensions(new ResponseTemplateTransformer(true)));


    @Before
    public void setup() {

        RestAssured.port = wireMockRule.port();
    }

    @Test
    public void exampleTest() {

        byte[] bodyBytes = given()
                .when()
                .get("/documents/document/123")
                .then()
                .statusCode(200)
                .extract().response().body().asByteArray();
        assertEquals(739L, bodyBytes.length);

    }
}

If the transformer is not global, then it's OK.

The mapping was:

{
  "request": {
    "method": "GET",
    "urlPattern": "/documents/document/.+"
  },
  "response": {
    "status": 200,
    "headers": {
      "Content-Type": "application/pdf"
    },
    //the base64 encoding of the content of /src/main/resources/wiremock/__files/minimal.pdf
    //unfortunately we cannot use bodyFileName="" because of https://github.com/tomakehurst/wiremock/issues/247
