Critical Path not working as expected



Our team is importing primavera p6 schedule into our system which use dhtmlx gantt.
I have checked the tasks and task links are both imported correctly, but the critical path is not showing as it is in primavera p6.
Are there anyways to debug or check what is wrong on calculating the critical path?
And also is there any plan to directly import an p6 schedule which is in .xer format.



Hi jacob. were you successful in integrating primavera p6 to gantt chart ?
