An uncaught Exception occurred on "main" thread.

Answer 1

The problem was from node version, i updated the node and the problem solved!

Answer 2

The package.json file you posted is the wrong one.

There should be another one inside the app folder. It should look something likes this :

{
  "name": "name",
  "main": "app.js", //THIS IT THE ENTRYPOINT
  "version": "X.X.X",
  "author": {
    "name": "Name",
    "email": "[email protected]"
  },
  "description": "some desc!",
  "repository": {
    "url": "https://github.com/yourrepo"
  }
}

Verify that the entry point file exists (it has to be a .js file and not a a typescript file) and you should be good to go.

Answer 3

the entry point is defined in angular.json

"architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/output",
            "index": "src/index.html",
            "main": "src/main.ts",

but error like this can happen if we have any compile errors, I had it with tests and sub application, I excluded it in tsconfig and now it works

Answer 4

In my case it was related to my NativeScript CLI version. Updated the version and the issue was solved. Just for reference I was at angular-cli 7.3.6 and NativeScript-cli 5.4.0 (got the issue) updated to NativeScript-cli 5.4.2 to solve the issue. Anyone facing the similar issue, try updating your NativeScript CLI version.
