Here's a crazy idea. Take the following simple example (in javascript):

    var m = [[1], [2], [3]];
    // ... a lot of code in between, perhaps m was passed through
    // several functions without TypeScript type declarations, so you might mistakenly
    // think m is a simple array like [1, 2, 3] at this point...
    var m2 = [];
    m.forEach(x => {
 m2.push(x); //# [[number], [number], ...] will be the form of m2 here

	it "the state 'Completed' should be tracked correctly", :js => true do
	visit show_video_path(:unit_id => @unit.id, :channel_id => Channel.first.id, :w => 600, :h => 450)
	puts "--- trying to click video ---"
	#page.find("div.vjs-big-play-button").click #click play video button
	find(:xpath,'//div[contains(@class,"vjs-big-play-button")]').click #click play video button -- alternative find method
	# some more code, not being reached during execution...
	puts "---"
	end
