I had the same exact problem with mongodb, unfortunatly it warn for modules that are not strictly required. An easy and quick solution to your problem, in your next.config file ignore these warnings:

module.exports = {
  webpack: (config) => {
    config.resolve.fallback = {
      "mongodb-client-encryption": false ,
      "aws4": false
    };

    return config;
  }

I got the same error too. All I did was run the below command (which installs the aws4 module) and all was solved.

npm install aws4
