Error "Missing dependency …… in search path"

[remitbri]

Hello

I'm using ReScript 11.1.4 and extension 1.63.6

I have several modules in the style of

module FooBar = {
  let make = React.lazy_(() => Js.import(FooBar.make))
}

module App = {
  @react.component
  let make = () => {
    <div>
      {React.string("Foobar: ")}
      <FooBar />
    </div>
  }
}

where FooBar is another (existing) module.

The compiler running in the terminal is perfectly happy. If I open the module containing the code above in VSCode it's fine. But as soon as I edit the module, I've got an error from the extension displaying "Missing dependency FooBar in search path" at the beginning of the file. If I reload the module, no extension error until I edit the module. And again, the compiler in the terminal shows zero problem.

It's more an annoying than a stopping issue, sure (it took me, err, months to open the issue)

So you've narrowed it down to when there are "overlapping" modules like that?

(the issue has to do with incremental typechecking)

Indeed. In fact, I used to have just in the App module when I was still using ReScript v10

module App = {
  @react.component
  let make = () => {
    <div>
      {React.string("Foobar: ")}
      <LoadableFooBar />
    </div>
  }
}

and in the LoadableFooBar

module type FooBarType = module type of FooBar

@val
external FooBarType: module(FooBarType) = "undefined"

include unpack(FooBarType)

@val
external import: (@as("./FooBar.mjs") _, unit) => Js.Promise.t<'a> = "import"

let make = ReactLazy.make(() =>
  import() |> Js.Promise.then_((module(FooBar: FooBarType)) =>
    Js.Promise.resolve({"default": FooBar.make})
  )
)

and it was rewritten to the code at the beginning when I moved to v11, and that's when the extension error appeared
(…I think. It might have appeared at a later extension update. Sorry!)
