Exceptions are not handled

[shahidiqbal12]

Hi,
I'm using this wrapper for g2w stats collection and is working fine for active tokens but if the token gets expired, the execute method throws exception:

Method LogMeIn\GoToWebinar\Exception\GoToWebinarException::__toString() must not throw an exception, caught Error: [] operator not supported for strings
Is there any way to handle the exception and refresh the access token if expired.

Thanks.
