Unable to add attachments to JIRA Issue using Mule 4

[Jayesh V Naik]

Hi Team,

I am using the REST API to attach files to the Jira Issue using Mule 4. I have replicated the exact request generated in POSTMAN. I do get a 200 response from JIRA REST API, but the attachments do not get uploaded.

Below is my request:

Headers :

{
"Authorization" : "Basic XXXXXXXXXXX",
"Content-Type" : "multipart/form-data; boundary=----WebKitFormBoundary8Qdad9adas9dfd8df",
"X-Atlassian-Token" : "no-check"
}

Body:

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="sampleMule.pdf"
Content-Type: application/octet-stream

Hi Jayesh,

I am not familiar with using Mule, however perhaps I can help with more of the aspects that Jira Cloud's REST API is expecting here.

In my own testing, I have been able to upload attachments using the REST API in Jira Cloud, but when I do this, I wasn't using the 'application/octet-stream' that you appear to being using here.  Instead I have been referencing a binary file directly by filename, and then reference that filename location as found on my local machine.  There are some other good examples of this on Community such as https://community.atlassian.com/t5/Jira-questions/How-do-I-upload-attachment-to-JIRA-Issue-via-REST-API/qaq-p/545073

That said, I did notice that your WebKitFormBoundary string in the header does not appear to match the string in the body.  I believe that these will need to match in order for Jira to understand the body contains an attachment in that form.

Try adjusting that first.  If that doesn't resolve this, then I would be interested to see if we can learn the exact response that Jira returns when making this call. I know you mentioned it provided a 200 code, which should be a good sign.  However Jira should also be providing a comprehensive response in json format that details filename, id, author, etc.  An example can be see in Jira Cloud REST API Reference: Add attachment: POST /rest/api/3/issue/{issueIdOrKey}/attachments.  If we can see the details of that response perhaps we can learn more here about what is happening when trying to upload such attachments in this case.
