When using the "errors" package, using `%+v` (extended format), each Frame of the error's StackTrace will be printed in detail. Let's only print `%v` to print the error. If the error has a Cause it will be printed recursively. Basically `%+v` has been replaced with `%v` for all `error` type interfaces, whether the logger is Info, Warning or Error.
