}

It is not at all clear what the problem is or what to check so I have no idea what to do next

Seems to be related to lit-html having an export map and possibly this plugin trying to read package.json by importing it from the package, which is not allowed

Seems like Vite uses

import resolve from 'resolve'
...
resolve.sync(id)

for this and that one can properly resolve lit-html/package.json

https://github.com/vitejs/vite/blob/f3a0c3b72c3483808d5649efbcc8118927a9d0b4/packages/vite/src/node/utils.ts#L140-L153

It seems that package.json cannot be read because of this reason, the export in the package.json file is not defined.

A version option can be added to eliminate this problem,

shared:{
  "lit-html": {
           version: "^2.6.1"
        }
}
