You must call `.manage()` before using this command | Tauri Apps | Page 1

Hi, I have some problems with state management, I have several states and there is no problem with them, but with this one (VaultMeta) there is and I don't understand why.

I've seen other discussions on this topic and haven't found a similar error myself.

Thank you for your answers

main.rs

mod vaults;

#[path ="./structs/vault_meta.rs"]
mod vault_meta;

fn main() {

    let vault_meta: VaultMeta = match vault_meta::load_or_init() {
        Ok(v) => v,
        Err(err) => {
            match err {
                ...
            }
            return ();
        }
    };

  .manage(AppState { pass: Default::default() })
