GraphQL operations is undefined
Hi, I'm having an odd case where the GraphQL operations are undefined when the multipart form request is parsed. We're using Google Cloud Functions at the moment. It works fine in my local GCF emulator but the deployed cloud version is always returning `undefined`.

**The code in question is:**

```
// Decode the GraphQL operation(s). This is an array if batching is
// enabled.
console.log( 'operations', operations )
operations = JSON.parse(operations)
```

As a result, the server logs the following:

```
...
SyntaxError: Unexpected token u in JSON at position 0 at Object.parse (native) at form.parse
...
Error: Request aborted at form.parse (/user_code/node_modules/@jstwrt/apollo-upload-server/lib/main/index.js:58:25)
```

Line 58 being `form.parse(request, (error, { operations }, files) => {`

Has anyone else experienced this issue. If someone could lead me in the right direction, that'd be helpful, thanks.
