Hello,
I wasn’t experiencing this issue in Rolldown version 1.0.1, but as soon as I updated to 1.0.2, it started occurring in all subsequent versions. The issue identified by the Claude AI agent is believed to be caused by the JSON-from-schema API feature in the ZOD and LangChain packages, so the following setting was added to the Rolldown configuration.
treeshake: {
// Zod v4 + LangChain: keep these side-effectful, else Rolldown's finalizer panics
// ("init_from_json_schema is not in any chunk", rolldown 1.0.2–1.1.0) and at runtime
// drops PURE-annotated Zod class constructors ("Class is not a constructor").
moduleSideEffects: [
{ test: /(^|[\\/])(zod|@langchain|langchain)([\\/]|$)/, sideEffects: true },
{ external: true, sideEffects: true },
],
},When I add this to the config, the build completes without any issues and the bundle file works. I can’t provide a source link because the code is in a private repository.
The RollDown versions where I encountered the issue: 1.0.2 - 1.0.3 - 1.1.0
