I have a script that identified two records that I need to update. My query returned the two _id values as: 62bdca65a69a2cdf17978992 and 62c06c18d694a13c4a29c078. I generated update the statements:

db.people.updateOne({_id: ObjectId('62bdca65a69a2cdf17978992')}, {$set: {dept: 22}});
db.people.updateOne({_id: ObjectId('62c06c18d694a13c4a29c078')}, {$set: {dept: 22}});

Only one got updated and examination of the data showed that one has the _id: 62bdca65a69a2cdf17978992 and the other has the _id as ObjectId('62c06c18d694a13c4a29c078').

1. Can I somehow determine if the "ObjectId" part of the _id exists so that I can dynamically include or exclude that in my update?
2. Can I write the update statement in a generic way so both get updated?
