Unable to send linked issue keys in slack notification

[Andrew]

Hi Team,

I am trying to create an automated rule that can send a slack notification where the message will contain both the issue key and the linked issue key. The issue that I am facing is that the linked issue key is not coming through on the message. I am following the smart values documentation but does not seem to work or I am doing something wrong.

I am using the JSON extension to find the linked issue fields. When I navigate to the linked issue, in the footer it gives me the following 

fields.issuelinks[0].outwardIssue.key

 I added this to the slack message using the different combos

{{issue.fields.issuelinks[0].outwardIssue.key}}

{{fields.issuelinks[0].outwardIssue.key}}

{{issuelinks[0].outwardIssue.key}}

None of the above worked and no key is being sent in the slack notification.

Any help or guidance would be much appreciated

I managed to figure it out. I removed the [0] and that did the trick ;)
