Hi,

I would check the app_plugin files have been copied over as part of the build (should happen when you build or run dotnet build).

app_plugins.

There should be a uSync folder in app_plugins e.g

if these aren't copying then there probably something broken 😔 your build/package process

break the cache

Also you could increment the version for the runtime minification (this will break any caching of the js files that Umbraco might have made)

In your appsettings.json file. under the "Umbraco" section.

  "RuntimeMinification": {
    "Version" : "2"
  }

run in debug

to confirm you could run in debug, and instead of caching the files Umbraco will return them individually.

again in the "Umbraco" section of the appsettings.json file

  "Hosting": {
    "Debug": true
  },

if there is anything wrong with the files / code this should at least pinpoint which file is the problem.
