Your issue seems to be related to not updating the Shakapacker version in your package.json. Ensure you have the exact same version of Shakapacker in Gemfile and package.json.

Indeed after updating shakapacker version in package.json the error has been solved.
Closing the issue is fine, thank you for your support!
