Extra coders seem to be getting recognized, but their results aren't used

[reinux]

I have a couple coders for single-case unions:

let itemIDEnc (ItemID id) =
  Encode.string id
let itemIDDec : Decoder<ItemID> =
  Decode.map ItemID Decode.string

let extras =
  Extra.empty
    |> Extra.withCustom itemIDEnc itemIDDec
    |> Extra.withInt64

And I receive it fairly straightforwardly:

  let cmd = promise {
    return! Fetch.tryPost(Routes.query, q, extra = JsonCodecs.extras)
  }
  m, Cmd.OfPromise.perform
      (fun () -> cmd :?> JS.Promise<Result<QueryResult, FetchError>>) ()
      (fun r -> QueryResultReceived (TabID 1, r))

QueryResult has a couple int64s in there, so it'll complain if I don't have the withInt64 in there, but it still loses precision, and the other ItemID just takes on a raw string value, which causes an invalid access exception later on when I try to retrieve the value.

The same coders work fine on the encoder side.

What could be going on here?

[MangelMaxime]

Which version of the library are you using?

Because, since version 2, we do have tests for extra coder and then seems to all pass.

[reinux]

That's odd... I'm using 2.0.0.

[MangelMaxime]

Then I have no idea, can you please try to add a failing test?

Because right now I can't really help as according to the tests it should be supported 🤷‍♂️

[reinux]

Hmm... I'm trying to build Thoth.Fetch on my machine, but I keep getting an error with fake build:

Script reported an error:
-> BuildFailedException: Target 'YarnInstall' failed.
-> One or more errors occurred. ('yarn install' task failed)
-> 'yarn install' task failed

[MangelMaxime]

Do you have yarn installed on your machine?

Can you please try to set Fake to be verbose? I think it is with --verbose.

Does yarn install work if you execute it manually?

[reinux]

fake --v build output (where it errors out):

I tried yarn install too, but yarn also crashes with a few warnings and then an error:

[MangelMaxime]

Ok, so this is a problem with the oniguruma dependency and your environnement...

I think you are using a newer version of Node.js than me.

Can please clean your repro git clean -xdf and then try to run yarn upgrade to force an upgrade all the dependencies. Perhaps a fix has been released in one of them...

[reinux]

No luck, same error on yarn upgrade as with yarn install :(

I wonder if this is only happening for me, and if it's maybe a corrupt Python install or something.

[MangelMaxime]

I can't really help you much more then...

I will configure this repo to support https://gitpod.io/ so you will be able to work on it without installing anything on your machine all from your browser.

[reinux]

Thanks, I appreciate the effort.

I'll try installing it on my laptop machine when I get a chance. I have to update VS and a bunch of other stuff in order to get it to work.

[MangelMaxime]

I am blocked by an issue where Dotnet Core complains about "Permission denied" on Gitpod... I open a discussion to try to solve it because it is not the first time I have this problem but I never really understood how to fix it.

So the environment will take some time to be available.
