Start Date and Other Gantt-Chart Data Missing in Team Managed Project

Question

When using WBS Gantt-Chart for Jira in a team-managed project, values such as start and end dates are not displayed.
Even after entering and saving the schedule, the schedule disappears upon reloading.

Answer

You need to add the fields mapped in the global issue setting of WBS Gantt-Chart for Jira to the team-managed project.

Due to API specification changes in Atlassian Cloud, which began rolling out in late February 2025, team-managed projects can now only retrieve data from fields that have been explicitly added to the project.

As a result of this restriction, if fields such as the start date are not added to the team-managed project, WBS Gantt-Chart for Jira will be unable to retrieve their values.
