Error when editing 3rd party Video field

Whenever I hit save on the 3rd party field edit page it returns the following error:

The default value PHP code returned an incorrect value
Expected format :

array(
0 => array('embed' => value for embed, 'value' => value for value, 'provider' => value for provider, 'data' => value for data),
// You'll usually want to stop here. Provide more values
// if you want your 'default value' to be multi-valued :
1 => array('embed' => value for embed, 'value' => value for value, 'provider' => value for provider, 'data' => value for data),
2 => ...
);

Returned value :

Any help would be appreciated.
