The server was unable to process the request cannot be processed by the Service

During the process of WCF programming, a request that cannot be processed by the service is caused by an internal error.

The details are as follows:

The server was unable to process the request due to an internal error. for more information about the error, either turn on includeexceptiondetailinfaults (either from servicebehaviorattribute or from the <servicedebug> Configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft. net Framework 3.0 SDK documentation and inspect the server trace logs.

Error:

The request cannot be processed due to an internal error.

Solution:

Configure the error attribute in Service Behavior:

Add the following code to the service class:

[Servicebehavior (includeexceptiondetailinfaults = true)]

This is before the service class.
