I am using Sailfish as template engine in Rust:

https://rust-sailfish.github.io/sailfish/getting-started/

I followed the simple tutorial and have the following code:

#[derive(TemplateOnce)]
#[template(path = "index.stpl")]
struct HomeTemplate {
    messages: Vec<String>
}

let ctx = HomeTemplate {
    messages: vec![String::from("foo"), String::from("bar")],
};

println!("{}", ctx.render_once().unwrap());

The code itself works fine and the program runs fine.

However, VSCode has this constant error and the #[derive(TemplateOnce)] line is underlined in red:

failed to load file `/Users/XXXXXXXX....XXXX/server/target/debug/build/sailfish-compiler-19a8f501817d4158/out/templates/460671ab72c8d6b8-8a0fdd098792c13e`
rust-analyzer macro-error
core::macros::builtin
macro derive

It seems like something is wrong with my VSCode or my rust analyzer? I am not sure.

I tried cargo clean but the issue has persisted. Also tried restarting VSCode.

EDIT: Is my issue similar to the one this person is facing with include! macro gives failed to load file error?:

Or could it be similar to this?
