Getting "UnhandledPromiseRejectionWarning: Error" in quick start and in example code for bulkReadDocuments

Question

Using the Quick Start from the Domino AppDev Pack documentation, I get an error:

(node:46496) UnhandledPromiseRejectionWarning: Error

Error occurs in line:

const response = await database.bulkCreateDocuments(createOptions);

Same error I get in the example code of the database.bulkReadDocuments.

To find better error messages, you should catch the error being thrown.

try {
  const response = await database.bulkCreateDocuments(createOptions);
} catch (e) {
  console.error(e);
}
