Problem
You receive a message stating “Worklog must not be null”
Solution
Please ensure that Worklog Visibility is not set in the Log Work Dialog.
If you see Restricted to at the bottom of the dialog, it might be that someone has configured the Default Worklog Visibility Group in the add-on configuration.
While in Jira System Configuration, Comment visibility is set to default Project Roles only, and may need to be changed to Groups & Project Roles. Please see Configuring Jira application options for more information.
