Cannot get Time Remapping + LoopOut to work without blank keyframe(tried all the fixes)

[markwm]

Whenever I enable time remapping and use loopOut() I get the last frame as a blank keyframe. 

I've read all the solutions to fix this but they are not working for me. Going back 1 frame, creating a new keyframe and deleting the previous last keyframe simply moves the blank frame. No matter where the last keyframe is, it creates a blank frame. 

How can such a simple task be so frustrating?

When you enable Time Remapping, the last keyframe is set after the last frame instead of at the start of the last frame. Go to that frame using the "k" key, and you will always have an empty frame. Move back one frame (Ctrh/Cmnd + left arrow), and set a new keyframe using the diamond in the keyframe navigator in the timeline. You will see something in that frame. Move forward one frame now using the "k" key, and the comp panel will again be empty. Delete that keyframe using the diamond or the delete key, and then use the J and K keys to jump back and forth between the two Time Remapping keyframes. You should always see something in the comp panel. Add a loopOut() expression, and you will get a looping video.

I am having exactly the same issue. Even when I add a new keyframe and delete the final keyframe, there's still a blank frame.

I've tried using ExtendedLegacy Script.

I've tried using different LoopOut() variations:

- loopOut()

- loopOut(type = "cycle", numKeyframes = 0)

I've tried installing beta software. 

I've tried in a new project file.

Any suggestions would be appreciated
