Autocomplete is not working

[anquegi]

Description

I get this error on messages:

Company: An error occurred in auto-begin
Company: backend company-capf error "jsonrpc-error: "request id=17 failed:", (jsonrpc-error-code . -32603), (jsonrpc-error-message . "no type check results"), (jsonrpc-error-data)" with args (candidates Newt)

Repro steps

THis is my configuration, I'm using MAC OS X catalina and dotnet 3.1

;;; my-fsharp.el --- fsharp configuration -- lexical-binding: t; --
;;; Commentary:
;;
;;; Code:
(use-package fsharp-mode
:defer t
:ensure t)
(add-to-list 'auto-mode-alist '("\.fs[iylx]?$" . fsharp-mode))

(require 'eglot-fsharp)

(setq inferior-fsharp-program "dotnet fsi")

(require 'dotnet)
(add-hook 'fsharp-mode-hook 'dotnet-mode)

(provide 'my-fsharp)

;;; my-fsharp.el ends here

Expected behavior

After M-x eglot, it start well ,

[eglot] Connected! Server EGLOT (FSNetCore/fsharp-mode)' now managing fsharp-mode' buffers in project `FSNetCore'.

I'm creating the project from here https://docs.microsoft.com/es-es/dotnet/fsharp/get-started/get-started-command-line

Actual behavior

but then start error with autocomplete

Did you restore your project: dotnet restore?

Could you provide the content of your *EGLOT (PROJECT_NAME/fsharp-mode) events* buffer?

sprintf "I used to be %s but now I'm %s thanks to JSON.NET!" value (JsonConvert.SerializeObject(value))

I can reproduce the issue. Adding -v to the fsautocomplete.dll parameters reveals:

[Checker] ParseAndCheckFileInProject - /home/juergen/fsharp/FSNetCore/src/Library/Library.fs completed with errors [unknown (1,1)-(1,1) parameter error Assembly reference 'mscorlib.dll' was not found or is invalid
