Error : java.lang.Nullpointerexception: Cannot invoke method Trim()

Question

I have tried using Port and baseUri and does not run the rest, always fails.

Complete error:

java.lang.NullPointerException: Cannot invoke method trim() on null object at org.codehaus.groovy.runtime.NullObject.invokeMethod(NullObject.java:91) at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:47) at org.codehaus.groovy.runtime.callsite.Callsitearray

Project code:

package br.com.academia.poo;

import static com.jayway.restassured.RestAssured.given;
import static org.hamcrest.Matchers.containsString;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import com.jayway.restassured.RestAssured;

@RunWith(SpringRunner.class)
@SpringBootTest
public class AcademiapooApplicationTests {

    public AcademiapooApplicationTests() {
        RestAssured.baseURI = "localhost:8080/" ;
    }

    @Test
    /* Chama o serviço pelo metodo POST */
    public void testCriaUsuario() {
        String myJson = "{\"id\":\"1\",\"name\": \"vanessa\"}";

        given()
            .contentType("application/json")
            .body(myJson)
        .when()
            .post("/clientes")
        .then()
            .statusCode(200)
            .body("message",containsString("usuário criado com sucesso"));
    }

    /*

The error you are getting says that you are calling the TRIM method in through a string that has not been initialized with any valid value, probably a NULL, look for your error there by the Pogometaclasssite file in the call method next to line 47.
