Trigger Match Expression for updatedAt

[Todd_Stephenson]

Hey @Tyler_Kaye , Thank you for the quick reply.

edited: I didn’t have the trigger active, oops. Sorry!

issue:
On insert it triggers the function 3 times. Here is my function:

exports = function(changeEvent) {
  const dbName = changeEvent.ns.db;
  const collectionName = changeEvent.ns.coll;
  const collection = context.services.get('mongodb-atlas').db(dbName).collection(collectionName);
  const currentDate = new Date();

  // Check the operation type
  if (changeEvent.operationType === 'insert') {
    // If it's an insert, set both createdAt and updatedAt
    collection.updateOne(
      { _id: changeEvent.documentKey._id },
      {
        $set: {
          createdAt: currentDate,
          updatedAt: currentDate
        }
      }
    )
    .then(result => {
      console.log(`Inserted document in ${collectionName} collection with createdAt and updatedAt fields.`);
    })
    .catch(error => {
      console.error('Error setting createdAt and updatedAt on insert:', error);
    });
  } else if (changeEvent.operationType === 'update') {
    // If it's an update, only set updatedAt
    collection.updateOne(
      { _id: changeEvent.documentKey._id },
      {
        $set: {
          updatedAt: currentDate
        }
      }
    )
    .then(result => {
      console.log(`Updated document in ${collectionName} collection with updatedAt field.`);
    })
    .catch(error => {
      console.error('Error setting updatedAt on update:', error);
    });
  }

  return;
};
