Add Jira-native linked Issues to Issue Picker

Issue Picker does not add issues, which are already linked natively in Jira to the Issue Picker custom fields.

You can, however, create an automation that checks for natively linked issues and add them to the issue picker custom field:

...

Syntax: Lookup issues

Code Block
issue IN linkedIssues({{issue.key}}, "is blocked by")

Here issues with the Issue Link Type “is blocked by“ are added to the Issue Picker custom field.

Syntax: Edit issue fields

Code Block
{ "fields": { "customfield_10075": [{{#customfield_10075}}"{{.}}",{{/}}{{#lookupIssues}}"{{key}}"{{^last}}, {{/}}{{/}}] } }

Here the Issue Picker Field is customfield_10075.

Notes:

Please make sure that the issues added via the automation also confirm to the Issue Picker JQL condition. As the field is edited directly, the JQL condition cannot be enforced by Issue Picker at this time.
Please make sure that the natively linked issues are also in the scope of the automation rule.
Vary the trigger of your rule according to your needs (trigger periodically or when issue link is changed on the issue).
