wp.data.dispatch( ‘core’ ) returns null

    I am following the tutorial “Build your first block” and have a folder structure representing the scaffold created by the npx @wordpress/create-block@latest command.

    Using it as my starting point, I’m trying to retrieve the WordPress core store to add an entity, but I keep getting the error “Uncaught TypeError: Cannot read properties of null (reading ‘addEntities’)”.

    Here is the whole src/index.js file with the code I have added starting at import { dispatch } from '@wordpress/data'; (scaffold comments removed for brevity).

    import { registerBlockType } from '@wordpress/blocks';

import './style.scss';

import Edit from './edit';
import metadata from './block.json';

registerBlockType( metadata.name, {
	/**
	 * @see ./edit.js
	 */
	edit: Edit,
} );

import { dispatch } from '@wordpress/data';

dispatch( 'core' ).addEntities( [
	{
		name: 'programs',
		kind: 'amilia/v1',
		baseURL: 'amilia/v1/programs',
	},
] );

    It appears dispatch( 'core' ) returns null and I have no idea why. Should I be calling it in a different place?

    Ah, need to put dispatch code in a hook…

    import { dispatch } from '@wordpress/data';
import { addAction } from '@wordpress/hooks';

addAction('plugins.pluginRegistered', 'amilia/register-programs-entity', (() => {
	dispatch( 'core' ).addEntities( [
		{
			name: 'program',
			kind: 'amilia',
			baseURL: '/amilia/v1/programs',

		},
	] );
}));
