These scams have enormous scale. The Economist has a fascinating podcast about it. The full series requires a subscription, but it is worth at least listening to the first 3 free episodes. https://www.economist.com/audio/podcasts/scam-inc
I don’t know if this fits your particular situation, but I recommend building tutorials into your migration process. I built a tool for migrating apps from Heroku to AWS ECS. The app developer runs the tool in their repository and it opens a migration guide in their web browser. The actual migration was mostly automated but we split it up into steps and embedded them into the guide. This way we could teach app devs the basics of how to use ECS and other AWS services as they went. We could also link out to additional docs and provide company specific details. There was a CLI mode for developers that had to migrate a bunch of apps. The tool was a big success and a couple hundred apps were migrated with it. The migration guide ended up being a good reference for people building brand new apps in AWS too. I built the guide using VuePress, but Docusaurus is also a good option if you are familiar with React.
There is also the built in Image Capture app that works with most flatbed scanners or printer/scanner combos. It has its own quirks, but works better than any manufacturer software I’ve ever tried.
You can use the debugger from Chrome dev tools to debug Node.js. Just run node with the `—-inspect-brk` flag, open `about://inspect` in Chrome, and select your app under remote targets. This has saved me tons of debugging time. See also: https://nodejs.org/en/docs/guides/debugging-getting-started/
