): Record<string, any> {
  const result: Record<string, any> = {};

  for (const [key, value] of Object.entries(obj)) {
    if (typeof value === 'object' && value !== null) {
      result[key] = replaceUndefinedValuesWithNull(value);
    } else {
      result[key] = value === undefined ? 'undefined' : value;

      if (value === undefined) {
        console.log('FOUND UNDEFINED', key, value, result[key]);
      }
