Error: JSON deserialization error (Android)

## Issue

I am getting `JSON deserialization error` with the following on Android **ONLY** - iOS is working as expected.

```
export const config = {
issuer: 'https://opentest.coros.com',
clientId: 'XXX',
clientSecret: 'XXX',
redirectUrl: `com.myapp.staging://oauth`,
scopes: ['userInfo', 'runData'],
serviceConfiguration: {
authorizationEndpoint: `https://opentest.coros.com/oauth2/authorize`,
tokenEndpoint: `https://opentest.coros.com/oauth2/accesstoken`,
revocationEndpoint: `https://opentest.coros.com/oauth2/deauthorize`,
}
}

const result = await authorize(config)
```

Response I am expecting (I got this via iOS as it works):
```
{
"refreshToken": "XXX",
"scopes": [],
"accessToken": "XXX",
"idToken": "",
"tokenAdditionalParameters": {
"openId": "XXX"
},
"tokenType": "",
"authorizeAdditionalParameters": {},
"accessTokenExpirationDate": "2022-08-19T10:24:57Z"
}
```
I have a hunch it's related to the `tokenAdditionalParameters` but I'm not 100% sure.

Worth noting I can't see any network request to COROS using Flipper.

## Environment

* **Your Identity Provider**: COROS (https://coros.com/)
* **Platform that you're experiencing the issue on**: `Android`
* **Are you using Expo?** No

Start at the authorize(config) Android path and investigate the JSON deserialization failure around the COROS token response, especially tokenAdditionalParameters. Compare the Android handling with the working iOS response; done means authorization succeeds on Android and returns the expected token fields.
