After enabling dark feature for async webhook and restarting Jira, webhook payloads fail to send Parent Link data

Issue Summary

After enabling the dark feature for async webhook and restarting Jira, webhook payloads fail to send Parent Link data.

This is reproducible on Data Center: yes

Steps to Reproduce

1. Setup a webhook destination in Jira
   • Admin > System > Webhooks
2. Enable the webhook debug
   • Admin > System > Logging and Profiling > Set com.atlassian.webhooks with debug verbose log)
3. In Jira software enable the async webhook dark feature
   • In jiraurl/secure/admin/SiteDarkFeatures!default.jspa add/enable the "com.atlassian.jira.webhookEventsAsyncProcessing.enabled" dark feature
4. Restart the Jira instance

Expected Results

The webhook payload is completely populated.

Actual Results

The custom field "Parent Link" is not populated as expected.

Below we have the payload when:

• sync webhook is being used (without the async dark feature and Jira restarted):

  The custom field 10108 relates to Parent Link

• async webhooks is used and restart your Jira (before restart it will not fail)

  ...
  customfield_10108: null
  (...)
  

  The custom field 10108 relates to Parent Link. Note the custom field 10000 ("Development") did not present data as well.

Workaround

Disable async webhooks and restart Jira:

• Go to jiraurl/secure/admin/SiteDarkFeatures!default.jspa and disable the "com.atlassian.jira.webhookEventsAsyncProcessing.enabled" dark feature
• Restart the instance.
