  try {
    if (!input) throw new IngestkoreaError({
      code: 401, type: 'Unauthorized',
      message: 'Invalid Credentials', description: 'Access Token Expired'
    });

    const contents = { message: 'Verfiy Token Success' };
    return {
      statusCode: 200,
      headers: { 'content-type': 'application/json; charset=utf-8' },
      body: JSON.stringify(contents, null, 2)
    };
  } catch (err) {
    let customError = new IngestkoreaError({
      code: 500, type: 'Internal Server Error',
      message: 'Something Broken', description: 'Unhandled Error'
    });

    if (err instanceof Error) customError.error.description = `${err.name}: ${err.message}`;
    if (err instanceof IngestkoreaError) customError = err;

    const contents = { ...customError };
    return {
      statusCode: contents.error.code,
      headers: { 'content-type': 'application/json; charset=utf-8' },
      body: JSON.stringify(contents, null, 2)
    };
  };
};

(async () => {
  const response = await sampleAPIResponseFunction(false); // (true | false)
  console.log(response)
})();
