End sequence in timeline after incorrect response and go to next

[maranut]

Hi to all!
I'm quite new to coding with Javascript and was trying to adapt an experiment. In the experiment (a digit span task, this one here), the participant is presented a series of digits and then asked to recall the digits in the correct order. I want the experiment to continue to the next part of the experiment once the participant has recalled a series of digits incorrectly. I've found some information suggesting jsPsych.endCurrentTimeline(); but implementing this ends the entire experiment:

var forward_response_block = {
  type: 'single-stim-button',
  stimulus: response_grid,
  button_class: 'submit_button',
  data: {
    trial_id: "response",
    exp_stage: 'test'
  },
  on_finish: function() {
    jsPsych.data.addDataToLastTrial({
      "response": response.slice(),
      "sequence": curr_seq,
      "num_digits": num_digits,
	  "repetition": rep_num,
      "condition": "forward"
    })
    var correct = false
      // staircase
    if (arraysEqual(response, curr_seq)) {
      feedback = '<span style="color:green">Correct!</span>'
		if (rep_num == 1){
		  rep_num += 1;
		  stims = setStims()
		} else {
		  num_digits += 1
		  rep_num = 1
		  stims = setStims()
		}
		correct = true
    } else {
                feedback = '<span style="color:red">Incorrect</span>'
                jsPsych.endCurrentTimeline();		       
    }
    jsPsych.data.addDataToLastTrial({
    correct: correct
    })
    response = []
  },
  timing_post_trial: 500
}

Additionally, I then tried to split up the timeline into multiple timelines so that only the corresponding timeline is stopped by jsPsych.endCurrentTimeline(). But this throws the following error: "Trial level node is missing the "type" parameter. The parameters for the node are: ..."
This is the part of the code that I changed:

var intro = [];
var forward = [];
var between = [];
var reverse = [];
var end = [];

intro.push(instruction_node);
for (i = 0; i < num_trials ; i++ ) {
	forward.push(start_test_block)
	forward.push(test_block)
	forward.push(forward_response_block)
	forward.push(feedback_block)
}
between.push(attention_node)
between.push(start_reverse_block)
for (i = 0; i < num_trials ; i++ ) {
	reverse.push(start_test_block)
	reverse.push(test_block)
	reverse.push(reverse_response_block)
	reverse.push(feedback_block)
}
end.push(post_task_block)
end.push(end_block)

jsPsych.init({
             timeline: [intro, forward, between, reverse, end],
             display_element: "getDisplayElement",
             fullscreen: true,
             on_trial_finish: function(data){
               addID('digit-span')
             },
...
      });

I've found some similar questions with jsPsych.endCurrentTimeline() on here but unfortunately I still can't figure out how to fix the issue. Maybe someone on here knows how to help, I would appreciate it!
Thanks so much in advance!
