I am currently trying to set up the Jira plugin for Mattermost and I have been running into an issue with trying to create a Jira Issue or attach a comment to a Jira Issue.
I was able to successfully connect my Mattermost account to my Jira account and I am able to receive notifications from Jira. The error that pops up when I try to create an issue is the following message:
method GET is not allowed, must be POST
I understand what the error is, but I’m not sure quite how to fix it. I tried searching online to see if someone ran into a similar issue, but no luck. If you need more info please let me know.
