Module error when using Javascript

I keep getting error when using the Javascript module and using

I tried using the require and import ES6 syntax and both did not work.

here is the error when using import

Since I was following Kestra documentation for JavaScript plugin npm will default to the latest package which is currently 0.20.0-SNAPSHOT

The temporary fix is to use the previous version in npm explicitly - "npm i @kestra-io/libs@0.12.0" To fix it, it looks like the code should be updated to ES6 syntax, remove type:"module" from the package.json, or rename index.js to index.cjs in order to continue using CommonJS with "type":"module" in package.json

I am encountering an error when attempting to run the following Kestra flow, which is designed to execute a Node.js script using the @kestra-io/libs library within a Docker container.
