All, 

I have build a custom visual that works as expected. Now I am trying to use the formatting utility and have following all the intructions in the link https://github.com/Microsoft/powerbi-visuals-utils-formattingutils/blob/HEAD/docs/usage/installation.... I have followed every single step in this guide but when I try to import the valueFormatter, I get the error "Namespace powerbi.extensibility has no exported member utils"

  //pbiviz.json
    "externalJS": [
        "node_modules/powerbi-visuals-utils-typeutils/lib/index.js",
        "node_modules/powerbi-visuals-utils-dataviewutils/lib/index.js",
        "node_modules/powerbi-visuals-utils-formattingutils/lib/index.js"
    ]

//tsconfig.json
{   
    "compilerOptions": {
        "allowJs": false,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "target": "es6",
        "sourceMap": true,
        "outDir": "./.tmp/build/",
        "moduleResolution": "node",
        "declaration": true,
        "lib": [
            "es2015",
            "dom"
        ]
    },
    "files": [
        "./src/visual.ts",
        "node_modules/powerbi-visuals-utils-typeutils/lib/index.d.ts",
        "node_modules/powerbi-visuals-utils-dataviewutils/lib/index.d.ts",
        "node_modules/powerbi-visuals-utils-formattingutils/lib/index.d.ts"
    ]
}

I am sure I am doing something wrong, and would appreciate if you could help me fix this

Thanks
