There are a few options.  
You would need to check if the ID is a valid one.  
See this question:

> <https://stackoverflow.com/questions/7483089/wrong-objectid-in-mongo>

You could also remove and add this ID again using `db.collection.remove({"_id":"yourInvalidId"})`.

Let me know if this helped 🙂
