What am I missing here?

Here is the code im using:

import { useState, useEffect } from 'react'
import { useDataset, useDocumentOperation, useFormValue } from 'sanity'
import { toHTML } from '@portabletext/to-html'

export function SetAndPublishAction(props: any) {
    const { patch, publish } = useDocumentOperation(props.id, props.type)
    const [isPublishing, setIsPublishing] = useState(false)
    const documentData = useFormValue([props.id, "country"])
    const dataset = useDataset()

    useEffect(() => {
        // if the isPublishing state was set to true and the draft has changed
        // to become `null` the document has been published
        if (isPublishing && !props.draft) {
    }, [props.draft])

    return {
        disabled: publish.disabled,
        label: isPublishing ? 'Publishing' : 'Publish & Update',
        onHandle: () => {
            // This will update the button text

            // Set publishedAt to current date and time
            patch.execute([{ set: { name: "hello world" } }])
            console.log("logging test here: ,", dataset)

            // Perform the publish

            // Signal that the action is completed
and this is the config:

export default defineConfig({
  name: 'default',
  title: 'escape-cms',

  projectId: '*****',
  dataset: 'production',

  plugins: [deskTool(
      structure: myStructure,
      defaultDocumentNode: defaultDocumentNodeResolver,
  ), visionTool()],

  document: {
    actions: (prev: any) =>
      prev.map((originalAction: any) =>
        originalAction.action === 'publish' ? SetAndPublishAction : originalAction

  schema: {
    types: schemaTypes,

Any help would be much apreciated.

That hook accepts a

I also tried this. Which does not work either..
const documentData = useFormValue([props.type as string, "name"])

Spamming this alittle.. But guessing the obvious work-around here is useClient to get the data...
