Calling Option::unwrap() on a None value recorded in Rocket app

[whatevernot]

Hello - I have a simple Rocket app which is displaying errors on my endpoint declarations. Example:

#[get("/foo/<d>")]
fn get_foo(d: &RawStr) -> String {
    format!("get_foo:::: {}", d)
}

This results in an error (and ugly red text) "called Option::unwrap() on a None valuerust-analyzer[macro-error]".

I am stumped.

rust-analyzer version:

• 0.2.940

rustc version:

• rustc 1.61.0-nightly (3b348d932 2022-02-19)

rustup version:

• stable-x86_64-unknown-linux-gnu unchanged - rustc 1.58.1 (db9d1b20b 2022-01-20)
• nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.61.0-nightly (3b348d932 2022-02-19)

I've tried various versions of rust-analyzer and they all seem to exhibit this error.

Any help is appreciated - the code works fine by rust-analyzer flags all my endpoints as errors.

Thanks a bunch.
