Building with error "Path or pattern "**/*.html" did not match any files"

[ddddm]

After implementing some basic dynamic pages, like this:

// site/pages/category/data.js
module.exports = function() {
    return [
        {
            "title": "This is title",
            "body": "This is content",
            "filename": "category/foo"
        },
        {
            "title": "This is another title",
            "body": "This is content",
            "filename": "category/bar"
        }
    ]

};

i've restarted broccoli-taco serve and now it keeps failing with the Error: Path or pattern "**/*.html" did not match any files

Here is what what i get in the console:

MBP-dddm:static-site ddddm$ broccoli-taco serve
