I’ve updated my project to the latest version of middleman 4…4.3 and I’m getting this error when trying to start the development server, everything is working well if I comment it out.

Thanks

Hello @tommaso.valentini16 and welcome to the community!

Unfortunately the Dato Middleman extension has been deprecated and we’re no longer supporting it: GitHub - datocms/middleman-dato: A Middleman extension to integrate your website with DatoCMS
So all errors generated from newer versions of middleman will not be patched as we’re no longer releasing newer versions for it.
