c# web-services sharepoint

I have a web service that is working fine in one environment but not in another.

The web service gets document meta data from SharePoint, it running on a server where I cant debug but with logging I confirmed that the method enters and exits successfully.

What could be the reason for the errors?

The error message is,

The formatter threw an exception while trying to deserialize the message: 

There was an error while trying to deserialize parameter http://CompanyName.com.au/ProjectName:GetDocumentMetaDataResponse. 

The InnerException message was 'Error in line 1 position 388. 'Element' 'CustomFields' from namespace 'http://CompanyName.com.au/ProjectName' is not expected. 

Expecting element 'Id'.'.  Please see InnerException for more details.

The InnerException was

System.ServiceModel.Dispatcher.NetDispatcherFaultException was caught Message="The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://CompanyName.com.au/ProjectName:GetDocumentMetaDataResponse.

The InnerException message was 

'Error in line 1 position 388. 
'Element' 'CustomFields' 
from namespace 'http://CompanyName.com.au/ProjectName' is not expected.

Are you sure your web service is deployed correctly to the enviornment that is NOT working. Looks like the type is out of date.
