typescript, error: "Debug Failure. False Expression" at forEachIdentifierInEntityName, typescript.js:24094:26

Question

Got this strange error when upgraded Typescript version from 2.8.4 to 2.9.2:

ERROR in ./js/main.ts
Module build failed (from ./node_modules/ts-loader/index.js):
Error: Debug Failure. False expression.

Here is my tsconfig.json:

{
  "compilerOptions": {
  "sourceMap": true,
  "noImplicitAny": true,
  "module": "es6",
  "target": "es6",
  "lib": [
    "es2017",
    "dom"
   ],   
  "allowJs": true,
  "allowSyntheticDefaultImports" : true,
  "experimentalDecorators": true
  }
}

Question: how can I get suitable error message and what am I doing wrong? And, I also saw this question, but I'm not satisfied with the solution and explanation - I need to use at least the same target and do not roll it back to 'es3', which is the default.

Answer 1

A web search finds TypeScript bug 24111, which is fixed in TypeScript 3.0.1. Try upgrading TypeScript. If the problem is still there, follow the process to file a new TypeScript bug.

Answer 2

Try to execute "npm i typescript" in the same directory as your project.
