I am part of the support team at cisecurity and I have been uploading certifications which then gets sent via an automated email and a ticket gets created within the Marketing department with the links for the files that I have uploaded. One of the links works but the other links produces an error because Jira adds a comma next to the attachment id. Nothing has been changed on the support side with the automation message, so I think this may be a bug within Jira.
I have added some screenshots below. Thank you for your help
