Trying to add attachments in jira issue using rest api but getting [] in body from nodejs.

[vishwajeet haldar]

Here is the code for better understanding, 

 const filePath = 'file.png';

  const stats = fs.statSync(filePath);
  const fileSizeInBytes = stats.size;
  const fileStream = fs.createReadStream(filePath);

  const formData = new FormData();
  formData.append('file', fileStream, { knownLength: fileSizeInBytes });
  const formDataHeaders = formData.getHeaders();
  const response = await fetch(`${baseUrl}/ex/jira/${cloudId}/rest/api/2/issue/TEST-103/attachments`, {
    method: 'POST',
    body: formData,
    headers: {
      Authorization: accessToken,
      Accept: 'application/json',
      'X-Atlassian-Token': 'no-check',
      ...formDataHeaders,
    },
  });

Hi @vishwajeet haldar

Here is the Atlassian cloud rest API documentation for the same https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-attachments/#api-rest-api-3-issue-issueidorkey-attachments-post

Hi, @Naveen Kumar, Thanks for your response, I followed the documentation, but I got an error: object is not iterable for FormData.

Well, I have found a solution that is working for me in Node.js without installing any additional library.

const formData = new FormData();    // no need to install for node 18.^ +.

const file = new Blob([fileBufferData]);  // creating a new Blob from fileBufferData

                                                                      // import { Blob } from 'node:buffer';

formData.append('file', file, filename);   // second parameter is Blob, third                                                                                        // parameter is filename. 

const url = `${baseUrl}/ex/jira/${cloudId}/rest/api/2/issue/${issueKey}/attachments`;

const options = {

           method: 'POST',

           headers: {

                 Accept: 'application/json',

                 'X-Atlassian-Token': 'nocheck',

                 Authorization: accessToken,   // `Bearer ${token}`

          },

    };

options.body = formData;

const response = await fetch(url, options);

return response.json();
