Attach File To Issue API Response Returning Empty Array

[Conor Murphy]

Hi,

I'm creating a custom form in which a user can create an issue and attach a file to this issue all in the same form. The first API call will create an issue and then using the API response, I grab the newly created Issue Id to attach their selected file using a second call to the Attach to Issue API.

I seem to be successfully calling to the issue, however, the file does not attach and I receive an empty array ( [] ) as a response.

My code is as follows:

 let fileForm = document.getElementById("fileToUpload");
 let file = fileForm.files[0];
 let formData = new FormData();
 formData.append("file", file);
 let attachment = formData;

 AP.request(attachmentApiUrl, {
 type: 'POST',
 headers: {
 'Authorization': 'Basic myUsername:myPassword',
 'X-Atlassian-Token': 'no-check'
 },
 contentType: 'multipart/form-data',
 data: attachment,
 success: (resp) => {
 console.log(resp) // returns "[]";
 },
 error: (resp) => {
 console.log(resp);
 }
 });

To be clear, I checked that the content of "file" and "attachment" 
is correct and I am getting the necessary values as needed.

Am I missing something here? I'm not using an backend process for reading the file, just a file input (#fileToUpload) and putting it into a formData object which I then send to the API.

Have you figured out your problem? I am running into this issue.
