Conditional loop based on correct vs incorrect trials.

[rbruno1]

Hi. I am trying to get my experiment to run a loop node only when the participant answers correctly. Right now, i have an infinite loop that i am trying to escape, which means that maybe the "last_trial_correct" is always evaluated as false? let me know if you guys see something wrong here. The problematic node is in bold

const practice_trial_3 = {
  timeline: [
  {type: 'audio-keyboard-response',
  stimulus: 'GatingStimuli_Dollar.wav',
  response_allowed_while_playing: false,
  trial_ends_after_audio: true,
  post_trial_gap: 250
  },
  { type:'html-button-response',
    stimulus: ["Press OK to type your answer, or Listen again to replay the sound"],
    choices: ['OK', 'Listen again'],
    post_trial_gap: 500,
    on_start: function(trial) {
      if (repeated) {
        trial.choices = ['OK'];
      }
    }
  }]
}

const practice_response_trial_3 = {
  type: 'survey-text',
  questions: [
    {prompt: "What word was she about to say? If you don't know or didnt hear, then type NR for no response"}
    ],
  post_trial_gap: 500,
  data: {
    task: 'response',
    correct_response: 'dollar'
  },
  on_finish: function(data) {
    data.correct = data.response.Q0.toLowerCase() == data.correct_response;
      },
}
      
const practice_feedback_3 = {
  type: 'html-button-response',
  choices: ['Go'],
  stimulus: function(){
    var last_trial_correct = jsPsych.data.get().last(1).values()[0].correct;
    if(last_trial_correct){
      return "<p>Nice job! You are ready for the real experiment, and make sure to check your spelling before submitting! Click <strong>Go!</strong> when you are ready.</p>"; // the parameter value has to be returned from the function
    } else {
      return "<p>You answered incorrectly. The speaker said the word <strong>Dollar</strong>. Let's try it one more time before the real experiment. Make sure to check your spelling! Click <strong>Go!</strong> when you are ready.</p>"; // the parameter value has to be returned from the function
    }
  }
}

**const practice_feedback_3_loop = {
  timeline:[practice_trial_3,practice_response_trial_3,practice_feedback_3],
  loop_function: function(data){
    var last_trial_correct = jsPsych.data.get().last(2).values()[0].correct;
    return !last_trial_correct;
  }
}**
