Error: the update operation document must contain atomic operators, when running updateOne

Error: the update operation document must contain atomic operators

So, you're trying to use the updateOne method in MongoDB to replace a document with another one, but you're getting the error message: "Error: the update operation document must contain atomic operators." Don't worry, I'm here to help you understand why this error is occurring and how to fix it!

Understanding the error message

First, let's break down the error message itself. "The update operation document must contain atomic operators." 🤔 What does that mean exactly? Basically, MongoDB requires that when you use the updateOne method, you need to provide an atomic operator to specify the modification you want to make to the document.

Example

Let's take a look at the command you're trying to run:

db.c20160712.updateOne( { "Attribute" : "good"}, {"Type" : "DVD", "Title" : "Matrix, The", "Released" : 1999, "Genre" : "Action"}, { upsert: true} )

The second argument in this command is the replacement document you want to use. However, since it doesn't contain any atomic operators, MongoDB throws an error.

Easy solution: Use atomic operators

To fix this error, you simply need to use atomic operators in your update command. Atomic operators are special symbols that you can use to specify the modification you want to make to the document.

For example, if you want to replace the entire document with a new one, you can use the $set operator like this:

db.c20160712.updateOne( { "Attribute" : "good"}, { $set: {"Type" : "DVD", "Title" : "Matrix, The", "Released" : 1999, "Genre" : "Action"} }, { upsert: true} )

In this updated command, we're using the $set operator to specify the modification we want to make to the document. Now, when you run this command, you should no longer see the "Error: the update operation document must contain atomic operators" message.
