Work Area start doesn't set when the playhead is one frame before work area end.

I have a script that sets work area start to playhead, but if doesnt set work area start to playhead when playhead it one frame before work area end.

Thank you 🙏

app.beginUndoGroup("Set Work Area to selected layers");
{
    // Get the current active composition
    var comp = app.project.activeItem;

    if (comp instanceof CompItem) {
        // Save the current work area start and end
        var currentWorkAreaStart = comp.workAreaStart;
        var currentWorkAreaEnd = comp.workAreaStart + comp.workAreaDuration;

        // Set the work area start and end to the composition start and full duration
        comp.workAreaStart = 0;
        comp.workAreaDuration = comp.duration;

        // Get the current playhead time (time indicator)
        var playheadPosition = comp.time;

        if (playheadPosition >= currentWorkAreaEnd) {
            // If the playhead is after or at the current work area end
            var newWorkAreaStart = playheadPosition;
            var workAreaLength = currentWorkAreaEnd - currentWorkAreaStart;

            // Set the new work area start to the playhead position
            comp.workAreaStart = newWorkAreaStart;

            // Set the work area end based on the previous work area length
            comp.workAreaDuration = workAreaLength;
        } else {
            // Otherwise, set the work area start to the playhead position and the end to the previous work area end
            
            comp.workAreaStart = playheadPosition;
            comp.workAreaDuration = currentWorkAreaEnd - playheadPosition;
        }
    } else {
        
    }
}

app.endUndoGroup();

(there are some mistakes in the main post, and i don't know if you can edit the posts)
Thank you

I thik it's the same issue as your previous post. Try replacing this:

comp.workAreaStart = playheadPosition;
comp.workAreaDuration = currentWorkAreaEnd - playheadPosition;

with this:

comp.workAreaStart = 0;
comp.workAreaDuration = comp.duration;
comp.workAreaStart = playheadPosition;
comp.workAreaDuration = currentWorkAreaEnd - playheadPosition;

I did set that at line 12 and 13, but it just doesn't work for some reason.

It seems to work for me, but I may not be testing it in the same way.

<edit>

Also, I put those lines at line 30.

Actually, just ignore everything I suggested. You code works fine for me, but I must not be testing the way you are.

It works with a different approach.

            var oneFrame = 1 / comp.frameRate;

            comp.workAreaStart = 0;

            comp.workAreaDuration = comp.duration;            

            comp.workAreaStart = playheadPosition;

            comp.workAreaDuration = currentWorkAreaEnd - playheadPosition + oneFrame;

            comp.workAreaDuration = comp.workAreaDuration - oneFrame;

also the issues happens when my frame rate is, 23.976, its just unable to set the work area duration correctly, but with 24 frames it works properly

I'll try that.
