Forking a model crashes

[silberistgold]

Great library. Looking into using this for our realtime form collaboration feature.

Doing a simple fork crashes using the latest Version:

import { Model } from "json-joy/esm/json-crdt";

const model = Model.withServerClock();

model.api.set({ foo: "bar" });

// this does not work
const forkedModel = model.fork();

Same behaviour when using toBinary() and fromBinary().

Any help would be greatly appreciated.

Environment:

json-joy 17.49.1
vite 6.3.5
pnpm 10.11.0

I completely forgot to include the error message I received:

Does this happen with "lib" import?

import { Model } from "json-joy/lib/json-crdt";

[silberistgold]

Yes, the "lib" import has the same behaviour.
