error: Unexpected literal type `path`

[simanacci]

I'm getting this error after upgrading to 18.1. validator = { version = "0.18.1", features = [ "derive" ] }, lazy_static = 1.4.0, regex = 1.10.5

lazy_static! {
    pub static ref NO_WHITE_SPACE: Regex = Regex::new(r"^[^\s]+(\s+[^\s]+)*$").unwrap();
}

#[derive(Debug, Deserialize, Validate, Serialize)]
pub struct Login {
    #[validate(
        required,
        length(min = 1, message = "Enter your Username"),
        regex(path = *NO_WHITE_SPACE, message = "Spaces aren't allowed")
    )]
    pub username: Option<String>,
}

    = note: the following trait defines an item `from_derive_input`, perhaps you need to implement it:

I'm experiencing the same issue. @simanacci Have you managed to fix it?

It's a bit odd, the sample from the issue works for me on master 🤔
