I am trying to upload a video on youtube using the V3 `Youtube.video.insert` API method. When I call the method I get the following error message: `Bad request: Request contains an invalid argument.`. Despite the error message my upload still appears in my personal YouTube account under My Videos. I am new to React Native and I'm struggling to understand the Youtube API docs, could someone please explain to me what I'm doing wrong or how could I fix it?

This is my current request:

```
let response = await fetch(
        'https://youtube.googleapis.com/youtube/v3/videos?key=' + API_KEY,
        {
          method: 'POST',
          headers: {
            'Authorization': 'Bearer ' + accessToken,
            'Accept': 'application/json',
            'Content-Type': 'application/json'
          },
          body: JSON.stringify({
            part: 'id,snippet,status',
            notifySubscribers: false,
            requestBody: {
              snippet: {
                title: 'YouTube Upload Test',
                description: 'Testing YouTube upload',
              },
              status: {
                privacyStatus: 'private',
              },
            },
            media: {
              body: 'file:///data/user/0/host.exp.exponent/cache/ExperienceData/Camera/video.mp4',
            }
          })
        }
      );

```

I tried taking everything out from `body:` but I got the same response.

Here are the links that I am using trying to understand:
<https://developers.google.com/youtube/v3/docs/videos/insert>
<https://github.com/googleapis/google-api-nodejs-client/blob/master/samples/youtube/upload.js>

**UPDATE:**

Ok, I think I figured out but I still don't know how can I attach the video file... this is my code now:

```
let response = await fetch(
    'https://youtube.googleapis.com/youtube/v3/videos?part=snippet&part=status&key=' + API_KEY,
    {
      method: 'POST',
      headers: {
        'Authorization': 'Bearer ' + accessToken,
        'Accept': 'application/json',
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        snippet: {
          title: "This is the title",
          description: "This is the description.",
        },
        status: {
          privacyStatus: 'private',
        }
      }),          
    }
  );

```
