No Web service configuration for this access path: "&1&2&3&4"

What causes this issue?

An HTTP request has called a URL access path on this system. This
access path is served by the SOAP Processor, but does not identify a
valid Web Service endpoint URL.

System Response

Since the incoming HTTP request did not address a valid Web Service
endpoint URL, the SOAP Processor couldn't process that request.

How to fix this error?

This problem could be caused by a missing Web Service endpoint
configuration on that system or by a wrongly configured Web Service
consumer application.
In case of a missing Web Service endpoint configuration follow the
instructions of the Implementation Guide of this Web Service Provider
application in order to create a valid Web Service endpoint
configuration.
In case of the wrongly configured Web Service consumer application
correct its settings in order to address a valid Web Service endpoint
URL.
