Helmut said over 3 years ago on Autocomplete with StimulusJS :
Hi David, okay, I didn't realize I could just put some Javascript in Index.js. So I put a console.log statement in there, but it doesn't show up when I run my problem app. However, on my smaller sample app that mimics your demo, I can put that same console.log statement in the Index.js file, and it DOES show up. 

So I think the Autocomplete installation just isn't working on my bigger app, since the code between my sample app and bigger app is pretty much identical except for a couple of different class names (Invoice for Book, Client for Author).  Do you know if there's a way to uninstall Autocomplete, and maybe start again? Or take other steps to troubleshoot why Rails (6.0.3) isn't seeing the library? 

Thank you!
