Server Error Message: Unexpected client version. Please update your app

[robbie888]

When running, the server responds with the following error, which crashes the script:

{
    "errorCode": 1337,
    "errorMessage": "Unexpected client version. Please update your app.",
    "errorDescription": "Too lazy to make custom error code",
    "logStatus": null
}
{'errorCode': 1337, 'errorMessage': 'Unexpected client version. Please update your app.', 'errorDescription': 'Too lazy to make custom error code', 'logStatus': None}

Attempted a few different versions, but am still receiving the same message. So, not really sure where to get the appropriate version number from, or if it's a larger issue than just the version number.
