Webservice Response Invalid

Hi

I’m getting this error on a WCF-BasicHttp port…

Details:”Unable to read the stream produced by the pipeline.

Details: The value ‘xsd:string’ is invalid according to its schema type ‘http://www.w3.org/2001/XMLSchema:QName’ – ‘xsd’ is an undeclared prefix. “.

Header of response…

<ns1:searchResponse soapenv:encodingStyle=”http://schemas.xmlsoap.org/soap/encoding/” xmlns:ns1=”urn:B8Addr” xmlns:soapenv=”http://schemas.xmlsoap.org/soap/envelope/“>
   <searchReturn xsi:type=”xsd:string” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance“>

How do I fix this?

Thanks

Alan
