My code is trying to run this
const calendarData = calender_ response[ calendars"]; const calenderID = Object. keys(calendarData)[o]; const busyTimes = calendarData[calenderID]['busy'] busy_intervals - busyTimes.map(time = ($(time.start], ${time.end])); But it keeps giving type error cannot convert undefined or bull to object I have all the variables set but not to sure what’s going on

The error message "TypeError: Cannot convert undefined or null to object" typically occurs when you're trying to access properties of an object that doesn't exist or is null. In your case, it seems like calendar_response['calendars'] might be undefined or null. Here's a breakdown of your code: 1. const calendarData = calendar_response['calendars']; - This line is trying to access the 'calendars' property of the calendar_response object. 2. const calendarID = Object.keys(calendarData)[0]; - This line is trying to get the first key from the calendarData object. 3. const busyTimes = calendarData[calendarID]['busy']; - This line is trying to access the 'busy' property of the calendarData object at the calendarID key. 4. busy_intervals = busyTimes.map(time => (${time.start}, ${time.end})); - This line is trying to create a new array busy_intervals by mapping over busyTimes and returning a string for each time object. If any of the objects or properties you're trying to access don't exist, you'll get a TypeError. To fix this, you should add checks to ensure that the properties you're trying to access exist before you try to access them. Here's an example of how you can do this:

if (calendar_response && calendar_response['calendars']) {
  const calendarData = calendar_response['calendars'];

  if (Object.keys(calendarData).length > 0) {
    const calendarID = Object.keys(calendarData)[0];

    if (calendarData[calendarID] && calendarData[calendarID]['busy']) {
      const busyTimes = calendarData[calendarID]['busy'];

      if (Array.isArray(busyTimes)) {
        const busy_intervals = busyTimes.map(time => (`${time.start}, ${time.end}`));
      }
    }
  }
}

if (calendar_response && calendar_response['calendars']) {
  const calendarData = calendar_response['calendars'];

  if (Object.keys(calendarData).length > 0) {
    const calendarID = Object.keys(calendarData)[0];

    if (calendarData[calendarID] && calendarData[calendarID]['busy']) {
      const busyTimes = calendarData[calendarID]['busy'];

      if (Array.isArray(busyTimes)) {
        const busy_intervals = busyTimes.map(time => (`${time.start}, ${time.end}`));
      }
    }
  }
}

In this revised code, each step is only executed if the previous conditions are met, which should prevent the TypeError from occurring.
