Office 365 Event Creation Error: 'Cannot read property 'request-id' of undefined'

The error 'Cannot read property 'request-id' of undefined' occurs when the 'innerError' property is not defined in the error object. In this case, it seems like there is an error while creating an event in Office 365 via Node.js.

To fix this error, you can check if the 'innerError' property exists in the error object before accessing its 'request-id' property. For example:

if (error.innerError && error.innerError['request-id']) {
  console.log('Error creating event: ', error.innerError['request-id']);
} else {
  console.log('Error creating event: ', error);
}

This will check if the 'innerError' property exists and then access its 'request-id' property only if it exists. If it doesn't exist, it will log the entire error object.
