The "Unexpected token u in JSON at position 0" error occurs when we pass an undefined value to the JSON. parse or $. parseJSON methods. To solve the error, inspect the value you're trying to parse and make sure it's a valid JSON string before parsing it.
This usually means that an error has been returned and that's not valid JSON. Check the browser developer tools console and network tabs. Turn on Debugging and (after reproducing the error) check the web server error logs.
How did you define your tasks.json? I encountered the same issue when I defined my tasks.json with default typescript type. Following changes in tasks.json worked for me based on the answer in link
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"taskName": "compile",
"type": "shell",
"command": "tsc -p tsconfig.json",
"group": {
"kind": "build",
