How to send a Content-Type form-data request using rest assured?

I need to invoke a form-data typed API using Rest Assured. Here is my code.

private Map<String, String> getFormParamsMap() {
  Map<String, String> formParams = new HashMap<>();
    formParams.put("creatorId", "Instructor1");
    formParams.put("creatorPlatform", "Web");
    formParams.put("creatoredSource", "File");
    formParams.put("creatoredType", "Auto");
    formParams.put("deckId", "5a605b472e02d86561172dad");
    formParams.put("userId", "kind");
    return formParams;
}

public void invoke() {
          response = given()
                    .header("Content-Type", "application/form-data")
                    .header(AUTHORIZATION_HEADER_NAME, accessToken) //Some API contains access token to run with the API
                    .headers(headers)
                    .formParams(getFormParamsMap()) // requestParamsMap here.
                    .when()
                    .post(invokingEndpoint);
}

When I execute this, I am getting the below error.

Message: java.lang.IllegalArgumentException: Don't know how to encode creatorPlatform=Web&creatoredType=Auto&deckId=5a605b472e02d86561172dad&creatorId=Instructor1&creatoredSource=File&userId=kind as a byte stream.

Please use EncoderConfig (EncoderConfig#encodeContentTypeAs) to specify how to serialize data for this content-type.
For example: "given().config(RestAssured.config().encoderConfig(encoderConfig().encodeContentTypeAs("application/form-data", ContentType.TEXT))). .."
Stack Trace:
io.restassured.internal.http.EncoderRegistry.encodeStream(EncoderRegistry.java:130)

When I use .config(RestAssured.config().encoderConfig(encoderConfig().encodeContentTypeAs("application/form-data", ContentType.TEXT))) in the invoke() method, it gives the result as below.

{
"status": 400,
    "message": "Content type 'application/x-www-form-urlencoded;charset=ISO-8859-1' not supported",
    "error": "Bad Request",
    "exception": "org.springframework.web.HttpMediaTypeNotSupportedException"
}

My request is not x-www-form-urlencoded type, it is form-data type. I can execute it using postman.

Appreciate your support on this.

Thanks.

I have solve this issue by using encodeContentTypeAs("multipart/form-data", ContentType.TEXT)

Ex:-

public void invoke() {
     response = given()
                .config(
                        RestAssured.config()
                                .encoderConfig(
                                        encoderConfig()
                                                .encodeContentTypeAs("multipart/form-data", ContentType.TEXT)))
                .headers(headers)
                .formParams(formParams)
                .when()
                .post(oAuthBaseURI).then().extract().response();
}

As far as I can tell, headers(headers) method replaces all headers, and then RestAssured uses x-www-form-urlencoded content type as default.

Try adding "Content-Type" header after the call to headers(headers).

Please add the consumer as well.

See here for the encoders available for Rest Assured. This might be causing the problem -

encodeContentTypeAs("application/form-data", ContentType.TEXT)

You can also try this - 

.encoderConfig(encoderConfig().appendDefaultContentCharsetToContentTypeIfUndefined(false).encodeContentTypeAs("application/form-data", ContentType.TEXT));
