Trying to create new custom checkbox input component in Sanity V3. But getting error in attached screenshot.import React from “react”;

// Important items to allow form fields to work properly and patch the dataset.
import { PatchEvent, set } from "part:@sanity/form-builder/patch-event";
import FormField from "part:@sanity/components/formfields/default";

// Import the TextInput from UI
import { Checkbox } from "@sanity/ui";

const Checkboxcomponent = React.forwardRef((props, ref) => {
  const { type, onChange } = props;
  return (
    <FormField label={type.title} description={type.description}>
        onChange={(event) => {
          console.log(event, "event");
          // onChange(PatchEvent.from(set(event.target.value)));

export default Checkboxcomponent;

aah, then there is nothing else I can help with sorry, don't know much about vite myself, just thought it might have something to do with the new way of creating custom components, but it seems you used the example code and if that still doesn't work then maybe its something else
