I can view draw.io diagrams in jira task but can't edit them. When I click edit button, it just shows draw.io icon and then nothing happens. It throws following errors in the browser console.
Uncaught SyntaxError: Unexpected token )

Could you repeat all the steps in Incognito mode and check if it is working, please?
Incognito mode should be cache and browser extension free so it is good for testing. Do you have edit permission?
P.S you are using Jira Cloud? Just to be sure.
The free version is a fixed code release that we cannot update. There will come a point when the Atlassian APIs change and our API calls are invalid. It's possible the last Jira Cloud release deprecated an API that codebase used.
If you don't want to pay you can download the attachment, edit it in www.draw.io and re-upload the changed attachment.
