Webpack Compilation Error - Function calls are not supported

[hopkinsjj9]

I've tried uninstalling/reinstalling ngrx/core and angularfire2 without success.

ERROR in Error encountered resolving symbol values statically. Function calls are not supported.
Consider replacing the function or lambda with a reference to an exported function (position 12:42 in the original .ts file),

I was able to backout the compose/store-freeze functionality in reducer.ts and compiled successfully.

//import {compose} from "@ngrx/core/compose";
//import {storeFreeze} from "ngrx-store-freeze";
....

export const reducer =
combineReducers({uiState,storeData, router: routerReducer});

Obviously, that's not the real solution. How can we get this functionality to work?

Without changing any code a recompile failed. This time on combineReducers. (see above)
No idea what's going on here

In src\app\reducer.ts

Try replacing:

//old code
//export const reducer = compose(storeFreeze, combineReducers)({uiState,storeData, router: routerReducer});

//new code
export function reducer(state, action) {
    return compose(storeFreeze, combineReducers)({ uiState, storeData, router: routerReducer })(state, action);
}

Many thanks Alucardz.
I will try using your suggestion. Hopefully, I can get the compose/store-freeze functionality working.
