Old IWS Plugin Stopped Working on 2022.2

I realize a lot has changed in the recent Indigo releases. Maybe you can point me in the right direction...

I have an old IWS Plugin that was working in 2022.1, that is located in:
/Library/Application Support/Perceptive Automation/Indigo 2022.2/Web Assets/plugins/

When I send a request to the plugin url, I receive an error message:

url: http://127.0.0.1:8000/myplugin/importData?param1-data1
Web Server Warning undefined page for request /myplugin/importData from 127.0.0.1

Has the URL syntax / location changed, or do you think I need to rewrite the plugin due to the new indigo web server or python changes?

Sorry, but I couldn't locate the documentation for this for the new version of IWS.

The old IWS plugins will not run in the new web server (we've been warning of their demise for years). The good news is that plugins can do everything (and more!) that the old IWS plugins could do. It's also possible that there's something out there that will do what you need.

Thanks. I missed that change (RTFM). I'll take a different approach.
