undefinedcreateProvider error when application starts

[rpk-red]

When I run npm start -s sometimes I get the following error when application starts:

Uncaught ReferenceError: undefinedcreateProvider is not defined
    at eval (webpack-internal:///./node_modules/react-redux/es/components/Provider.js:80)
    at Module../node_modules/react-redux/es/components/Provider.js (bundle.js:12222)
    at __webpack_require__ (bundle.js:725)
    at fn (bundle.js:102)
    at eval (webpack-internal:///./node_modules/react-redux/es/index.js:2)
    at Module../node_modules/react-redux/es/index.js (bundle.js:12330)

    at fn (bundle.js:102)
    at Module.eval (webpack-internal:///./src/index.js:6)
    at eval (webpack-internal:///./src/index.js:188)

Strange part is that this does not happen every time. On avrg it happens ever 3th time when I run command.

I suggest pasting your app's code into a fresh clone of slingshot to assure you have all the latest config.

It works now, problem was with some package version and i'm not sure witch one. But now I have new problem when i deploy application on azure I get the following error: Uncaught SyntaxError: Invalid regular expression: /^[Α-ω]+$/: Range out of order in character class at Object.<anonymous> (main.eb8e15138060192e8836.js:24) at n (main.eb8e15138060192e8836.js:1) at Object.<anonymous> (main.eb8e15138060192e8836.js:74) at n (main.eb8e15138060192e8836.js:1) at Object.<anonymous> (main.eb8e15138060192e8836.js:20) at n (main.eb8e15138060192e8836.js:1) at Module.<anonymous> (main.eb8e15138060192e8836.js:99) at n (main.eb8e15138060192e8836.js:1) at main.eb8e15138060192e8836.js:1 at main.eb8e15138060192e8836.js:1 Any idea what can be the problem?

[nickytonline]

@rpkRED, glad you got your initial error sorted out. If you build your prod build locally and run it via an package like http-server, does the app load? If so, I'd refer to Azure deployment documentation.

[rpk-red]

Problem was with validator.js it does not work after version 8.2.0 on azure for some reason. Downgrading it to 8.2.0 fixed the problem. Application worked with http-server, thank you for your help.

[nickytonline]

Great to here everything is sorted out.
