Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3"

ComponentFusionView? That is for sure not from the main grapesjs core, we don't have that component... Probably you're using some kind of modified version, so that might be the reason behind that error

Question

I tried to install new version but in my package.json nothing moves. It's on a plugin called "blocks avancées" of grapesJs but i have this issue on every folder when i try to run the code " ERROR in ../src/dom_components/view/ComponentFusionView.js Module build failed: Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version

Thanks for reporting this, @lebonsavane.

The error **Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version ** occurs when Components attempts to access properties before the component lifecycle is fully initialized. This is a common race condition in GrapesJS.

Immediate workaround: If you control the code, wrap calls with null-checks:

if (component && typeof component.method === 'function') {
  // your code
}

Root cause analysis: The Components doesn't validate state before invoking your method. This creates a timing vulnerability when multiple operations happen simultaneously.

Next steps:

  1. Try the null-guard workaround above
  2. Update to the latest GrapesJS — many race conditions have been fixed
  3. If this persists, share your exact reproduction steps with the team
  4. Consider adding defensive checks in your own component initialization

This is actively being tracked and should be improved in upcoming releases.
