Uncaught TypeError: Cannot set properties of null (setting '_isEditor')

Closing this as the demo seems to run fine, maybe something related to your browser cache/extensions

Thanks for reporting this, @RakulAgn.

Great question about Uncaught TypeError: Cannot set properties of null (setting '_isEditor'). The recommended approach with Canvas is to use the event-driven API.

Start here:

1. Check the GrapesJS documentation for your specific module
2. Look for the on() event listener method
3. Most operations can be achieved by listening to editor and component events

Common patterns:

// Listen for changes
editor.on('change', () => console.log('something changed'));

// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));

If you're still stuck:

• Share a minimal CodeSandbox reproduction
• Include what you've already tried
• Mention your GrapesJS version
