Error with listen function in custom Sanity composable

I try to run client.listen() but I get the error “listen is not a function”
Here is the code :

composable for loading and previewing data from sanity 
export default async function ({ query, params, livePreview = true }) {
	const mainStore = useMainStore()
	const sanityClient = mainStore.previewIsActive
		? {
				client: 'preview',
				server: false,
				initialCache: false,
		: undefined

	// live preview: listen to changes
	onMounted(() => {
		if (mainStore.previewIsActive && livePreview) {
			const sanity = useSanity('preview')
			sanity.client.listen(query, params).subscribe((event) => {
				setTimeout(() => {
				}, 900)

	// get data
	const { data, refresh } = await useLazySanityQuery(

	return data
Do you know why he tells me that
is not a function?
Thank you

I don’t have an answer, but am providing the source for context since most of these are custom hooks.
Have you pinned the client to the same version as the lock file of the template?
