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",
            "isDefault": true
        },
        "problemMatcher": []
    }
]
}
