mp4 video is in path, not playing, app crashing

[HeyCodeSnooper]

i have a video in my haxeflixel project named secret.mp4, for a little easter egg >:) and i get an error message on close when the FlxButton i made is pressed and crashes the game in the vscode terminal (screenshot attached)

this is the callback function that isnt finding the file.

function funny():Void
{
var funny:FlxVideo = new FlxVideo();
funny.onEndReached.add(funny.dispose);
funny.play("assets/videos/secret.mp4");
cutsceneTimer.start(12, donewithfunny, 1);
}

EDIT: the file IS there! (screenshot)
