Bug on node 12

[bidoubiwa]

For some reason when running the script in node 12 the events of the stream-json library are not waited on.

The following works well with node 14 > but not with node 12.

  await new Promise(function (resolve, rejects) {
    verifierStream.on('close', function () {
      resolve();
    });
    verifier.on('error', error => {
      rejects({message: `Json file is not valid: ${jsonFile}: ${error.message}`, file: jsonFile, error: error.message})
    });
  });
