Action Not Found For request 'GET /'

[EugeunieOrz]

Hello, I'm trying to run scala-play-react-seed and get the following errors:

1. Before updating packages in package.json loading localhost:9000 in browser gave me the following output:
   TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined

2. After updating packages in package.json I've got:

   Action Not Found
   For request 'GET /'
   These routes have been tried, in this order:
   1 GET / controllers.FrontendController.index()
   2 GET / api/summary controllers.HomeController.appSummary
   3 GET / $file<.+> controllers.FrontendController.assetOrDefault(file:String)

@EugeunieOrz, could you provide more context on this issue? environment details, which command you ran, etc.

In command-line on Windows 10 in ui folder of the project I ran npm install, after that I launched sbt in root project folder, then [scala-play-react-seed] $ run.

Afterwards, I've got the following:

`[warn] play-functional_2.12-2.8.1.jar no longer exists at C:\Users\eugen\Documents\scala-play-react-seed-master-before-update\null\Coursier\cache\v1\https\repo1.maven.org\maven2\com\typesafe\play\play-functional_2.12\2.8.1\play-functional_2.12-2.8.1.jar

I launched locakhost:9000 in the browser and got the following output:

Ideally, it should open the browser window on watch mode. Please check the status of the original issue.

I've the exact same issue on Windows (but on under Linux), with Play 2.8.8.
