@babel/polyfill is deprecated.

Help solve the problem. I am developing a project on a prod server.

Deploy in a Docker Swarm cluster.

Here are the steps in detail:

Create images of your application
Set these environment variables right before the following command:
TAG = prod
FRONTEND_ENV = production

Use the provided scripts / build.sh file with these environment variables:
TAG = prod FRONTEND_ENV = production bash ./scripts/build.sh

error return:

@ babel / polyfill is deprecated. Please use the necessary parts of core-js
and regenerator-runtime / runtime separately
killed

plese fix it in you code

I have the same issue when using 'docker compose up -d'.
Any update? Thanks you.

@babel/polyfill has been deprecated since babel version of 7.4.0.
@babel/polyfill is combination of core-js and regenerator-runtime but it tingly coupled to core-js@2 and cannot provide smooth migration to core-js@3
Official @babel/polyfill documentation

Solution:

import "@babel/polyfill";
=>
import "core-js/stable";
import "regenerator-runtime/runtime";
