Thanks for reporting this, @Akkiiiiiii.

The issue with Error: node_modules/grapesjs/dist/index.d.ts:12551:2 - error TS1005: '?' expected. 12551 }> ? C : {}) | undefined) => (editor: Editor) => void; ~ Error: node_modules/grapesjs/dist/index.d.ts:12558:3 - error TS1005: '?' expected. 12558 }> ? C : {}) | undefined) => (editor: Editor) => void; 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 β€” make sure components are fully loaded before you interact with them

  2. Use the editor's event system β€” 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) β€” this helps the team identify the root cause faster
  • Include GrapesJS version, browser, and console errors in your report
