The scope of this issue has changed with the way that configurations settings are no performed. However the error can still appear when reading a value that is not valid. The url can be parsed to see if its valid then return an error explaining the issue. Taking the response of url.Parse and wrapping it with a more meaningful error.

e.g.

_, err := url.Parse(address)
if err!= {
   return errors.WithMessage(err, "address must be a valid URL")
}
