Pass parameters from handler to NewError function?

[oliverdding]

I a some parameters from the request header, and want to return it in the response body whether the handler encountered error or not. But the NewError function generated do not accept another parameters but the error. How to do that?

Found a terrible solution:

func (service *CAPIService) HealthCheck(ctx context.Context, params gen.HealthCheckParams) (*gen.HealthCheckOutputBodyHeaders, error) {
	output, err := service.HealthCheckWrap(ctx, params)
	if err != nil {
		err = fmt.Errorf("timeout when pinging the database: %w", errors.New("My Variable"))
	}
	return output, err
}

func (service *CAPIService) HealthCheckWrap(ctx context.Context, params gen.HealthCheckParams) (*gen.HealthCheckOutputBodyHeaders, error) {
	... // real logic
}

func (service *CAPIService) NewError(ctx context.Context, err error) *gen.ErrorOutputBodyStatusCodeWithHeaders {
	MY_VAR := errors.Unwrap(err)
        ...
}

I think the library should expose a method to query the request.
