  = help: message: called `Result::unwrap()` on an `Err` value: Error("EOF while parsing a value", line: 1, column: 0)

repro code:

#[deno_bindgen::deno_bindgen]
fn greet() -> i32 {
    return 42;
}

Fixed by deleting bindings.json in project root

I'm having this issue come up. Deleting bindings.json (and the bindings/bindings.ts) did not solve for me.

= help: message: not implemented

the fix for me was to remove the '&' from the function signature, and changed

#[deno_bindgen]
fn my_init(inp:&i32) {}

to

#[deno_bindgen]
fn my_init(inp:i32) {}
