Getting exports from an evaluated module with get_module_namespace always results in null values

Trying to get module exports like the example here

The module is loaded with load_main_module, I call mod_evaluate on the ID returned, then do the below:

But the value returned is always undefined

Js:

    export function test() { return 2;}

    export function test() { return 2;}

    export function test() { return 2;}

    export function test() { return 2;}

Rust:

      let module_namespace = self.deno_runtime.get_module_namespace(module_id)?;
      let mut scope = self.deno_runtime.handle_scope();
      let module_namespace = v8::Local::<v8::Object>::new(&mut scope, module_namespace);

      let key = v8::String::new(&mut scope, "test").unwrap();
      let value = module_namespace.get(&mut scope, key.into()).unwrap();

      println!("{}", value.is_undefined()); // true

      let module_namespace = self.deno_runtime.get_module_namespace(module_id)?;
      let mut scope = self.deno_runtime.handle_scope();
      let module_namespace = v8::Local::<v8::Object>::new(&mut scope, module_namespace);

      let key = v8::String::new(&mut scope, "test").unwrap();
      let value = module_namespace.get(&mut scope, key.into()).unwrap();

      println!("{}", value.is_undefined()); // true

      let module_namespace = self.deno_runtime.get_module_namespace(module_id)?;
      let mut scope = self.deno_runtime.handle_scope();
      let module_namespace = v8::Local::<v8::Object>::new(&mut scope, module_namespace);

      let key = v8::String::new(&mut scope, "test").unwrap();
      let value = module_namespace.get(&mut scope, key.into()).unwrap();

      println!("{}", value.is_undefined()); // true

      let module_namespace = self.deno_runtime.get_module_namespace(module_id)?;
      let mut scope = self.deno_runtime.handle_scope();
      let module_namespace = v8::Local::<v8::Object>::new(&mut scope, module_namespace);

      let key = v8::String::new(&mut scope, "test").unwrap();
      let value = module_namespace.get(&mut scope, key.into()).unwrap();

      println!("{}", value.is_undefined()); // true
