    Rest Assured – Schema to use cannot be null

    May 30, 2025

    I’m working with Java and REST Assured to test REST APIs. I was trying the example with JSON schema validation but it throws this error:
    java.lang.IllegalArgumentException: Schema to use cannot be null

    at io.restassured.module.jsv.JsonSchemaValidator.validateSchemaIsNotNull(JsonSchemaValidator.java:270)
    at io.restassured.module.jsv.JsonSchemaValidator.access$300(JsonSchemaValidator.java:75)
    at io.restassured.module.jsv.JsonSchemaValidator$JsonSchemaValidatorFactory.create(JsonSchemaValidator.java:281)
    at io.restassured.module.jsv.JsonSchemaValidator.matchesJsonSchema(JsonSchemaValidator.java:166)
    at io.restassured.module.jsv.JsonSchemaValidator.matchesJsonSchemaInClasspath(JsonSchemaValidator.java:117)

    at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

    My test code is:
    given()
    .header(“Content-Type”, ContentType.JSON)
    //.header(“Authorization”, “Bearer ” + ConfigEnvironments.TOKEN_K8S)
    .body(jsonBody)
    .when()
    .post(ConfigEnvironments.BASE_URL_CLAIMENGINE +”/api/v1/FollowUp”)
    .then().log().all()
    .statusCode(202)
    .and()
    .body(matchesJsonSchemaInClasspath(“src/test/resource/followup-schema.json”));
