Hola @Katherine_Salazar_Te

Looks like the root cause is that the JavaScript method String.prototype.toWellFormed() is only available starting from Node.js 20—older Node versions will throw the exact error you’re seeing.

Here’s how to resolve it:

Upgrade Node.js to v20+

Your version is likely Node 18 or 19. Upgrade to at least Node 20. Or if using Docker, switch your base image to one that includes Node 20.

Clear existing license and restart:

After upgrading Node.
Then fully restart your n8n instance (Docker container, system service, etc.).

This ensures any old license state is removed before reactivating.

Reactivate license

  • If using a self-hosted instance, either:
    • Use the UI under Settings → Usage, paste your key and click Activate
    • Or set the environment variable.
    • and restart n8n (automatic activation at startup).
