Fault String

A Fault String is a descriptive message included in a fault response within a web service, particularly in protocols like SOAP. When a service encounters an error, it sends back this message to inform the client about what went wrong. Think of it as a brief, explanatory note that helps developers and users understand the nature of the fault without exposing technical details. The Fault String aims to clarify issues such as invalid input, server errors, or other problems, making troubleshooting easier and helping ensure proper handling or correction of the error.
