Hi, I believe there is a bit of a misunderstanding in how the match expression works (also, I am not convinced it is valid synctax with the $eq). I think this should work, but let me know if it is not what you are looking for:

{
    "$or": [
        {
            "operationType": "insert"
        },
        {
            "operationType": "update",
            "updateDescription.updatedFields.updatedAt": {
               $exists: false,
            }
        }
   ]
}
