@awais786327 I have looked at the site and it looks like that you need to add autoplay="true" in your video tag to make it play

Thanks for reporting this, @mohd7469.

The issue with Video throwing error appears to be a race condition or state management timing problem. This typically happens when component lifecycle events and DOM modifications overlap, creating an inconsistent state.

What to try:

  1. Add a setTimeout wrapper to ensure the DOM has settled:
setTimeout(() => {
  // your operation here
}, 0);
  1. Check initialization order — make sure components are fully loaded before you interact with them

  2. Use the editor's event system — listen to completion events:

editor.on('component:mount', (component) => {
  // safe to interact with component here
});

Recommended next steps:

  • Test with the latest GrapesJS version if you haven't
  • Provide a minimal reproducible example (CodeSandbox) — this helps the team identify the root cause faster
  • Include GrapesJS version, browser, and console errors in your report
