Store: Can't resolve all parameters for StateFactory: (?, ?).

[junimohano]

Can't run example app (https://github.com/ngxs/store/tree/master/integration)

Do I need to do something else ?

@salomoni when you create an issue on github it asks you to provide several pieces of information that are necessary for us to help you solve your issue

[jaripekkala]

@deebloo I don't quite follow, what's up?

Did you just upgrade to Angular 8? I'm getting a similar problem: Can't resolve all parameters for LoginComponent: (?, ?, ?)

[splincode]

@jtomek We can't reproduce, please create new issue if you have some problem

[gradzio]

@junimohano the solution is to add @Injectable() after @State decorator in your state. It fixed my errors after upgrading to angular 9

Thanks @gradzio adding @Injectable() after @State solved problem
