# Connected SDK Troubleshooting

> Fix common problems when integrating the Branch Connected SDK on Tizen and WebOS connected TV platforms.

### Minimum Requirements

- The Branch Connected SDK requires native browser Javascript and has only been tested in Tizen and WebOS with sessionStorage capability. No third-party libraries are needed to make use of the SDK as it is 100% native Javascript.

| Tizen | WebOS |
| --- | --- |
| 2.3 | 6.0 |

### Branch init Options

- Properties which you can pass within `branch.initSession()`
- Used for [Initialize Branch features](https://help.branch.io/developer-hub/connected-advanced-features.md#initialize-branch-features)

| Key | Value | Type | Required |
| --- | --- | --- | --- |
| advertising_ids | The current device's advertising id declared by the brand's corresponding key. Please refer to [Connected SDK Basic Integration](https://help.branch.io/developer-hub/connected-basic-integration.md#advertising-id-index) for more the key index. | `{string:string}` | **Y** for Ad Network Attribution<br>**N** for Web Based Attribution |
| branch_match_id | The current user's browser-fingerprint-id. The value of this parameter should be the same as the value of ?*branch_match_id (automatically appended by Branch after a link click). \_Only necessary if ?\_branch_match_id is lost due to multiple redirects in your flow*. | `string` | N |
| retries | default: 2 | `number` | N |
| retry_delay | expressed in milliseconds<br> default: 200ms | `number` | N |
| timeout | expressed in milliseconds<br> default: 5000ms | `number` | N |
| tracking_disabled | default: false | `boolean` | N |
| enableLogging | default: false | `boolean` | N |

### No Access-Control Error

- Make sure the Branch key is the same within the deep link and app.

```javascript
XMLHttpRequest cannot load https://api2.branch.io/v1/open. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 400.
```

### Browser Fingerprint ID

- In case you need to access your user's Browser Fingerprint ID for user deletion, use the function below.

```javascript
branch.getBrowserFingerprintId(function(err, data) { console.log(data); });
```
