well we're fucked. ts-json-schema-generator package is now ESM-only, (released in a non breaking version btw XD). I converted the entire kitajs codebase to ESM to keep it working but everything falls apart when the ts-plugin needs to be CJS because the tsserver is written in CJS and as cjs cannot import esm (for now), the @kitajs/ts-plugin cannot import any other kita esm package.
