Not able to run workflow with workflow_dispatch event with API call

I have not got one successful api call, not even with curl, not sure why! Tried like 20-30 times with different variants, etc. Getting the same 404 error each time.

import { Octokit } from '@octokit/rest'

(async () => {

	const owner = 'owner'

	await octokit.actions.createWorkflowDispatch({

gives
