Function traceError

cli/root.go:1512–1528

traceError is a helper function that aides developers debugging failed cli commands. When we pretty print errors, we lose the context in which they came. This function adds the context back. Unfortunately there is no easy way to get the prefix to: "error string: %w", so we do a bit of string manipul

(err error)

//
//nolint:errorlint
func traceError(err error) string {
	if uw, ok := err.(interface{ Unwrap() error }); ok {
		var a, b string
		if err != nil {
			a = err.Error()
		}
		if uw != nil {
			uwerr := uw.Unwrap()
			if uwerr != nil {
				b = uwerr.Error()
			}
		}
		c := strings.TrimSuffix(a, b)
		return c
	}
	return err.Error()
}
