Stuck on kashyyyk after defeating AT-AT and taking elevator down
After beating the ATAT on kashyyyk and taking the elevator down, I ended up near the entrance with the vine where you attack the storm troopers and then enter the boss battle against the purge trooper. I cannot enter through the door where you go after the purge trooper dies and I cannot go the other direction where you find the storm trooper saw killed because the vine is too far away and I don't have double jump. I am now stuck in the area with no way to advance.
Here is a video of someone else with the same problem
