Can I create tracker ticket with attachments?

Hello,
If there is no attached file, a Tracker Ticket is created normally.
However, if I try to include the attachment, I still get the datatype_mismatch error.
This error is occurs when a request is made to multipart/form-data.
Please help me how to use related_ticket_ids with attachments.
I attached my test code.

[Errors]

{"description":"Validation failed","errors":[{"field":"related_ticket_ids","message":"Value set is of type String.It should be a/an Array","code":"datatype_mismatch"}]}
{"description":"Validation failed","errors":[{"field":"related_ticket_ids","message":"It should contain elements of type Positive Integer only","code":"datatype_mismatch"}]}

Hi,
Welcome to our community!
We analysed the snippet and found that in the line meb.addTextBody(FreshdeskTicketField.RelatedTicketIds + "[]", idArray.optString(i), ContentType.MULTIPART_FORM_DATA.withCharset(UTF8)); , idArray.optString(i) will return a string and not an Array since idArray is an array of integers.

Hi~
Thank you for reply.
I have already tested both addTextBody and addBinaryBody.
Both failed, and the results are as follows.

addTextBody result : {“description”:“Validation failed”,“errors”:[{“field”:“related_ticket_ids”,“message”:“Value set is of type String.It should be a/an Array”,“code”:“datatype_mismatch”}]}
addBinaryBody result : {“description”:“Validation failed”,“errors”:[{“field”:“related_ticket_ids”,“message”:“It should contain elements of type Positive Integer only”,“code”:“datatype_mismatch”}]}

Can you tell me how to pass an integer array using MultipartEntityBuilder?
Or is there a way to solve this problem using another Java library?
Regards,

JSONArray idArray = data.getJSONArray(FreshdeskTicketField.RelatedTicketIds);
if (idArray != null && idArray.length() > 0) {
	for (int i = 0; i < idArray.length(); i++) {
		byte[] ticketIdBytes = ByteBuffer.allocate(4).putInt(idArray.optInt(i)).array();
		meb.addBinaryBody(FreshdeskTicketField.RelatedTicketIds + "[]", ticketIdBytes);
		meb.addTextBody(FreshdeskTicketField.RelatedTicketIds + "[]", idArray.optString(i), ContentType.MULTIPART_FORM_DATA.withCharset(UTF8));
	}
}

Hi @Myeongho_Lee,

We are not sure how the library works or any other libraries in Java. You can check on their repository or approach the contributors if it’s an open-source library or approach StackOverflow for help.

If the expected data-type is provided for the fields, the API will get succeed.

Thanks.
