REST API - Add an attachment during transition

Question

Hi. I was successfull to transition my issues from different states but I'm facing problems to transition them when it validates if I have uploaded an attachment.

I tried uploading the file before transition it but didn't work.

I did my research but couldn't figure out if is this possible to do, and if it is, how. Plese help!

from jira import JIRA
import requests
from requests.auth import HTTPBasicAuth

attachLocation = "C:\Users\ivan\attachments\"
attachFile = "text.txt"
attachmentURL = attachLocation+attachFile

parentCH = "CH-10101"

def upload_attachment (ch_issue_key, attachment, fname):
with open(attachment, 'rb') as attachment:
        url = "https://mycompany.jira.com/rest/api/2/issue/" + ch_issue_key + "/attachments"
        file = {"file": (fname, attachment, "application/octet-stream")}
        auth = HTTPBasicAuth('ivan', 'xxxxxxxxxxxxxxx')
        headers = {
"content-type": None,
            "X-Atlassian-Token": "no-check"
        }
        r = requests.post(
            url,
            auth=auth,
            files=file,
            headers=headers
        )
print("    status_code:", r.status_code)
print("
    ",r.text)
jira = JIRA(
 server="https://mycompany.jira.com/",
 basic_auth=('ivan','xxxxxxxxxxxxxxx')
)

issue_parent_ch = jira.issue(parentCH)
print(issue_parent_ch.fields.status) # This prints the issue status before transitioning it
status = str(issue_parent_ch.fields.status)

if status == "Completed":
    upload_attachment(issue_parent_ch.key, attachmentURL, attachFile)
    evidence = { "customfield_24678": "Closing issue" }
    transition = 111
    jira.transition_issue(issue_parent_ch.key, transition, fields=evidence)
print(issue_parent_ch.key + ": Moving from "Complete" to "Start review"")

You're right, my code is in spanish and I forget to translate that part when I posted it here, thanks for the observation (I edited the post and is OK now).

As you said the flow looks good but when I run this script I get the following out:

"Field Attachment is required"

C:\>python cerrar_ch.py

Completed || This is the issue status before transitioning it
status_code: 200 || This is the status when I upload the file

Maybe there is a way to upload the file during transition and not before as I'm dooing it in my code.

Hi @idanieri

Is this correct ...

fields=evidencia

shouldn't it be evidence? basically the flow should work like that, upload the image then transition or transition then upload; either way, it seems like a valid step to do. a user can upload an image then transition the issue or vice versa. What error messages are you getting or is there none?
