ParcelJS bundling error - favicon.ico: Invalid Version: undefined

This is the first time I am using ParcelJS. I npm it following their instruction everything looks good. So it would be the latest version. As soon as I run it against my project (a .html file with some js and css attached to it), I get this error.

favicon.ico: Invalid Version: undefined

I have tried to ask Google without much luck. Got any ideas?enter image description here


  • If you are using Parcel version 1.12.4 this github issue is the reason why you got this error. It's not your fault.

    You may try to pin your Parcel version as 1.12.3 in package.json:

    "dependencies": {
      "parcel": "1.12.3"

    If your Parcel is installed globally, you may check your version of Parcel:

    parcel --version

    Uninstall 1.12.4 and reinstall 1.12.3:

    npm uninstall -g parcel-bundler
    npm install -g [email protected]
