Support `readonly()` about zod-to-json-schema

Same issue here. Does readonly() affect the result or is it a ‘transparent’ definition , like .catch()?

zod-to-json-schema/src/parsers/catch.ts

Lines 1 to 7 in b8f2ac7

	import { ZodCatchDef } from "zod";
	import { parseDef } from "../parseDef";
	import { Refs } from "../Refs";
	export const parseCatchDef = (def: ZodCatchDef<any>, refs: Refs) => {
	return parseDef(def.innerType._def, refs);
	};

If it’s the latter, supporting .readonly() should be pretty straightforward. Happy to submit a PR if it makes sense.

UPD: This local patch seems to be working – I no longer get empty schemas 🎉

For simplicity, ZodReadonly is processed the same way as ZodCatch.

When is this gonna be released @StefanTerdell ?

Great, thanks @StefanTerdell! The new version works like a charm ✨

If you have a bit of time, can you please update the list of releases?

It should help Renovate (and other similar tools) show the list changes in autogenerated PRs. It is empty at the moment:
