Here you can choose fields which you want to let customers view. Please note that fields selected here needs to have value. If any of the fields does not yet contain value, it will not be displayed in the portal.
Save the selected fields. Now you can create a test request or use an existing request. Make sure to assign values to selected fields via issue edit screen if they are empty.
Is there any field missing from the list?
The add-on uses fields from Create Screen because of Jira API limitations.
Those read only fields with values will be displayed in portal request detail view.
