I've got a JSON object that's being submitted to a AWS Lambda NodeJS function. This JSON object has an apostrophe in one of the fields that I need to escape before it's being inserted into a MySQL database.

The object needs to stay intact as it's being stored as a JSON object in the database. I've looked at string replace functions but those won't work since this is a JSON object natively.

I'm sure there is a simple answer here, I'm just very new to NodeJS and haven't found a way after searching around for a few hours. Thanks in advance!

The field I need to update is 2.1 below:

**Example of the BAD JSON Object:**

```
{
  "field1": "ABCD1234DEFG4567",
  "field2": "FBI",
  "fieldgroup": {
    "1.1": "ABCD",
    "1.2": 20170721,
    "1.3": "ABCD",
    "2.1": "L'astName, FirstName M"
  }
}

```

**Example of the FINAL JSON object:**

```
{
  "field1": "ABCD1234DEFG4567",
  "field2": "FBI",
  "fieldgroup": {
    "1.1": "ABCD",
    "1.2": 20170721,
    "1.3": "ABCD",
    "2.1": "L''astName, FirstName M"
  }
}

```
