ngrx-undo | an undo library for ngrx/store | State Container library

I have an Angular4 application using ngrx. I created a undo higher-order reducer as documented on the redux website.

Unfortunately I am having issues with Ahead of Time (AoT) compilation when I apply this function in my root.reducers.ts file, and get this error

ERROR in Error encountered resolving symbol values statically. Calling function 'undoable', function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol rootReducer

The code works perfectly when AoT is turned off or after a file is modified, in which case just in time compilation is used.

I tried using ngrx-undo previously, but it didn't seem to work, which is why I rolled my own solution.

I've tried looking at other stackoverflow posts and searching google, but the majority of the other issues seem to be with 3rd party libraries or custom components, which aren't relevant in this case.

I know that I can fix the issue by removing the higher order reducer and converting cartReducer to be undoable directly, but that isn't desirable since we would have a lot of code duplication if we make any of the other reducers undoable.

How can I resolve this error? Preferably without removing AoT compilation, since that will be needed once we hit production.
