JSON Automation update a comment if there are pdf attachment

[Vandyck Lai Kai Yong]

I would like to auto update a comment whenever our agent include a pdf attachment in the response to customer. The update contains a newly appended user guide link on how to download / view the attachment.

This is the screenshot of my automation

This is the JSON format in my automation, but it does not work.

{
"update": {
"comments": [{
"set": "{{issue.comments.last.body.split(\",\").first.replaceAll(\"Change: ([0-9]*)\", \" https://apiit.atlassian.net/wiki/spaces/ITSM/pages/521371653/I+can+t+download+attachment+shared+via+Virtual+Help+Centre+ticket1\").concat(\"\\n\").trim()}}"
}]
}
}

I had reviewed these links on trying to solve my issue. Is it possible to achieve what I demand or is there any other way of doing it using automation?

Hi,

The edit issue API doesn't allow you update a comment as it isn't considered a field.

In the next day or so we will release the Edit Comment action which should enable you to do this.

Hello Nick,

Thank you for your explanation but I would like to know is there any alternative rather than just using automation to edit a comment when it detect pdf attachment? For example, some thing like an application extension?

Hope to hear from you soon.
