Adding attachment to Jira with Matlab RESTful API

I'm trying to add attachment to Jira issue from Matlab. The code below returns HTTP Status 200 OK, but the file is not added to the Jira issue. What is the reason for that?

import matlab.net.http.io.MultipartProvider
import matlab.net.http.io.FileProvider
import matlab.net.http.io.MultipartFormProvider


HeaderField = matlab.net.http.HeaderField('Authorization','Basic USERNAME:PASSWORD', 'Content-Type','multipart/form-data', 'X-Atlassian-Token','no-check');

fps = FileProvider("myfile.txt");
mp = MultipartProvider(fps);
formProvider = MultipartFormProvider("files",mp);

req = matlab.net.http.RequestMessage('post',HeaderField,formProvider)
req.send('https://XXX.atlassian.net/rest/api/2/issue/TEST-1/attachments')

I can add the attachment from windows command prompt using code (as instructed here: Atlassian document):

curl -D- -u USERNAME:PASSWORD -X POST -H "X-Atlassian-Token: no-check" -F "file=@myfile.txt" https://XXX.atlassian.net/rest/api/2/issue/TEST-1/attachments

Hi Juho,

Have you found a solution to this issue?

Hi Ray,

Unfortunately I haven't found solution for this.

Juho - since the CURL statement works, why not build that in MATLAB and use system to execute that statement?

userName = 'myUserName';
password = 'myPassword';
fileName = 'myfile.txt';
curlCommand = sprintf('curl -D- -u %s:%s -X POST -H "X-Atlassian-Token: no-check" -F "file=@%s" https://XXX.atlassian.net/rest/api/2/issue/TEST-1/attachments', ...
    userName, password, fileName);
[status, cmdout] = system(curlCommand);

Yes that would solve the problem. Thank you!
