Correct usage of restore when date is within array of objects about firestore-backup-restore HOT 2 OPEN

const applyConversion = (data: any, conversion: Function, key: Array<string>) => {
  if (!key || key.length === 0) return;

  if (Array.isArray(data)) {
    data.forEach(d => applyConversion(d, conversion, key));
    return;
  }

  if (!data.hasOwnProperty(key[0])) return;

  if (key.length === 1) {
    const theKey: string = key[0];
    const checkResult = conversion(data[theKey]);
    if (checkResult) data[theKey] = checkResult;
  } else if (isObject(data)) {
    applyConversion(data[key[0]], conversion, key.splice(1));
  }
}

//gives the properties of data, specified by keys, to conversion; keeps old value of conversion returns null, else replaces value with return value of conversion
export const convertProperty = (data: any, conversion: Function, keys: Array<string>) => {
  keys.forEach((key: string) => {
    applyConversion(data, conversion, key.split('.'));
  });
}

// Update date value
if (options.dates && options.dates.length > 0) {
  convertProperty(data, makeTime, options.dates)
}
