Can't instantiate packages

[farisd16]

I am trying to follow instructions from README.dev.md, but after running pnpm --filter=webidl-to-ts build, I get the error:

src/codegen.ts:994:13 - error TS2345: Argument of type 'NodeArray<ModifierLike>' is not assignable to parameter of type 'readonly Modifier[]'.
  The types returned by 'concat(...)' are incompatible between these types.
    Type 'ModifierLike[]' is not assignable to type 'Modifier[]'.
      Type 'ModifierLike' is not assignable to type 'Modifier'.
        Type 'Decorator' is not assignable to type 'Modifier'.
          Type 'Decorator' is not assignable to type 'StaticKeyword'.

Same, as a C++ emscripten user this error is totally unintelligible to me. It seems like has to do with the webidl library? Like we need a specific version of it?
