Как отладить проблемы с tsserver для vscode

Question

Premise

Проект, над которым я работаю, недавно начал переносить наш проект Javascript на Typescript.Возможность иметь типы - настоящее благословение, и она прекрасно работает с подсветкой синтаксиса / ошибок VScode.

$ code -v
1.30.0
c6e592b2b5770e40a98cb9c2715a8ef89aec3d74
x64

$ cat package.js (for the typescript in the vs code)
{
    "name": "typescript",
    "author": "Microsoft Corp.",
    "homepage": "https://www.typescriptlang.org/",
    "version": "3.2.2",
    ...

Проблема

В некоторых (обычно больших) файлах не отображаются ошибки типов Typescript.Например, эти две строки, добавленные в конец файла:

let a = 'a';
a = 5;

Должно отображать сообщение, подобное этому:

Тип '5' нельзя назначить типу 'строка'.ts (2322)

let a: string

Но для некоторых файлов это не так, а для некоторых файлов.

Подробно

Я пытался создать минимальный воспроизводимый случай, но пока кажется, что импорт из других файлов javascript (.js) как-то связан с этим.Я также проверил вкладку вывода для Typescript:

[Error  - 11:08:03 AM] 'getApplicableRefactors' request failed with error.

Я не могу понять, какой именно файл или строка вызывает проблему.Может ли кто-нибудь указать мне правильное направление?
