@awais786327 I am also struggling with uploading different assets. Maybe this can help. https://grapesjs.com/docs/modules/Assets.html#uploading-assets
@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:
- Add a setTimeout wrapper to ensure the DOM has settled:
setTimeout(() => {
// your operation here
}, 0);
-
Check initialization order — make sure components are fully loaded before you interact with them
-
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
