Is there any way to get the parser errors other than from console log

Usually, the error doesn't come from the parser but from the creation of the DOM (eg. the editor creates the element by using setAttribute). You can catch the editor's errors by listening to the log event Here, for example, you can put your logic (eg. by reading the error) and show the appropriate response

Question

I am using the latest GrapesJS (v0.16.27). As per the fix for the issue, (#2029) the exception has been caught and logged into the console.

Is there any way where we can get to know about the errors other than from console log?

Something similar to asset:upload:error, if we have parse:error, it would be helpful to handle the errors in a custom way. If we already have a way to handle this, please let me know.

editor.on('log:error', (err) => console.log('error from the editor', err))

Thanks for reporting this, @sathyanarayananaCES.

The issue with [Question] Is there any way to get the parser errors other than from console log 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
