Other Answers:

@ryansully -- inspectpack@1.3.2 is the correct, most up to date version, and within webpack-dashboard's semver range in package.json.

@tptee @kenwheeler -- We could bump package.json from "inspectpack": "^1.3.0", to "inspectpack": "^1.3.2", and we should update yarn.lock + package-lock.json files...

Side note -- we should get a procedure for maybe PRs to ensure both yarn.lock + package-lock.json are regenerated. Currently they have different versions of inspectpack and the package-lock.json file doesn't even meet semver requirements.
