Description
Starting with Lambda runtime version nodejs:22.v35, that corresponds to NodeJS v22.14.0, AWS has decided to stop supporting the ability to require ES modules.
This functionality was previously supported and advertised (see https://aws.amazon.com/blogs/compute/node-js-22-runtime-now-available-in-aws-lambda/) by AWS as an upgrade path strategy, for example for the middy.js middleware library (https://middy.js.org/docs/upgrade/5-6).
See here for more context: middyjs/middy#1288 (comment)
The reported reason for discontinuing it is an overall performance penalty impacting all workloads, not only those making use of the option.
The request is, simply, to try reintroducing the -experimental-require-module flag support in the new runtime version when it will be available.
Many thanks.
