Trying to get size report of already minified files

[JayBox325]

I have a sizereport task as follows:

gulp.task('sizereport', () => {
    return gulp.src('build/assets/**/*.*)
        .pipe(production(sizereport({
            gzip: true,
            minifier: function (contents, filepath) {
                if (filepath.match(/\.min\./g)) {
                    return contents
                }
            }
        })))
})

As all of my assets (Js, Scss etc) are being minified conditionally based on the environment in each of their own tasks. I was hoping this snippet above would pick up on those and show the .min versions alongside the non-minified versions.

However, I appear to be getting the following error:

TypeError: Cannot read property 'length' of undefined

    at Pumpify.EventEmitter.emit (domain.js:459:23)

When I change the source directory to just /build/assets/ I no longer get the error, but I also don't get the report.

Any help would be appreciated.

Thanks,
Jay

Hello,

Try returning something in the the minifier function.
