Error while crawling LOB contents in SP 2013:'Could not find default endpoint element that references contract in the ServiceModel client configuration section

Hi,

I created custom BDC Model using Visual Studio. In ReadList method i am getting data using Web Service call. Using this External Content Type (BDC Model) i created one external list and it is populating with data.

I created one new content source in search service application using this BDC Model and when crawled this content source i am getting the below error.

Error while crawling LOB contents. ( Error caused by exception: Microsoft.BusinessData.Runtime.RuntimeException MethodInstance with Name 'ReadList' on Entity (External Content Type) with Name 'Entity1' in Namespace 'bcsex.BdcModel1' failed unexpectedly. The failure occurred in method 'ReadList' defined in class 'bcsex.BdcModel1.EntityService1' with the message 'Could not find default endpoint element that references contract 'ServiceReference1.Service1Soap' in the ServiceModel client configuration section.

I included the bindings and client end point configuration settings in web.config file located at\\Inetpub\wwwroot\wss\VirtualDirectories\Port_Number, but still getting the same error.

Please help. Thanks a lot.
