Description

Is it possible to add or enlarge an existing example so as to include custom error messages that should be returned to the consumer of the API we build?

I'm not able to add a custom validator and add as well a application specific defined message that is more descriptive than:

{"error":"Key: 'Booking.CheckOut' Error:Field validation for 'CheckOut' failed on the 'required' tag"}%

Thanks!

Research direction

No file, test, or entry point is named. Start by locating the existing validation example in the examples repository and review how Gin exposes validator errors. Define the API-specific error-message behavior in the example, then verify that it returns the intended custom message.
