How to get VSCode to show me strict NullChecks Typescript errors

When I build my project with the following tsconfig.json

I get an error due to a recent addition strictNullChecks: true

.

{
    "version": "2.3.4",
    "compilerOptions": {
        "allowSyntheticDefaultImports": false,
        "removeComments": true,
        "strictNullChecks": true,
        "sourceMap": true,
        "jsx": "react",
        "target": "es5",
        "lib": [
            "es6",
            "dom",
            "scripthost"
        ],
        "outDir": "../build/"
    },
    "include": [
        "./*.ts",
        "./*.tsx",
        "./{client,mobile,server,shared,test,tools}/*.ts",
        "./{client,mobile,server,shared,test,tools}/*.tsx",
        "./{client,mobile,server,shared,test,tools}/**/*.ts",
        "./{client,mobile,server,shared,test,tools}/**/*.tsx",
        "./desktop/*.ts"
    ]
}

      

        
        
        
      

    

However, I don't see any errors in VSCode.

I also have the following vscode parameter:

"typescript.tsdk": "./node_modules/typescript/lib",

      

        
        
        
      

    

Everything seems to work fine in VSCode except for strictNullChecks errors.
