Summary

There is a single slack channel which is private and we are unable to see the watchers option for the project.

Environment

Jira Cloud

Steps to follow

• Check the slack channel configuration to see if the required Jira action ( Like issue created, updated) in included.

• Try replicating the issue from your side by creating a private slack channel adding to the customer instance.
• If the slack notification is created correctly for these Jira actions on slack, the next thing is to confirm if issue is replicable when an issue is created through slack using the commands or when an issue is created/updated through Jira.
• If the above works fine, check if there are other integrations which is creating this notification in slack.

Cause

Here the notification to Jira was being created by two integrations. One by Native Jira Slack integration and another one by Web hooks for this channel. The Web hooks too has the create event included.

The below snapshot shows where you can check for Web hook configurations Settings> System> Advanced.

Solution

For consistency you could just use one integration. Here, disabling web hooks notification for the channel solved the issue.
