@raclim @lindapaiste I have fixed few errors in this PR, but i don't know why the heck this sorting.field is returning undefined. Probably i need to look on this one and give you guys update as early as possible. I need to dig into the code and see where the fault lies ...

I do! The previous setSorting action took two arguments setSorting(field, direction). In the action creator function we restructured that into payload with two properties. https://github.com/processing/p5.js-web-editor/blob/7e0827805db71868151bdc7783385992446cc859/client/modules/IDE/actions/sorting.js#L8-L16

The new setSorting action creator that is auto-generated from createSlice takes one argument and that argument becomes the action.payload.

You're going to have the same problem with the setSearchTerm action which also currently takes two arguments setSearchTerm(scope, searchTerm).

There's two ways to fix it:

1. Find every place in the code where we call the setSearchTerm action and replace the action calls setSearchTerm(scope, term) with setSearchTerm({ scope, query: term }).
2. Make it so that the setSearchTerm action still accepts two arguments using the prepare feature of createSlice: https://redux-toolkit.js.org/api/createSlice#customizing-generated-action-creators

   reducers: {
   setSearchTerm: {
   reducer: (state, action) => {
     const { scope, query } = action.payload;
     state[`${scope}SearchTerm`] = query;
   },
   prepare: (scope, query) => ({ payload: { scope, query } })
   }
   }

I'm using setSearchTerm as the example there instead of setSorting because when I looked to see where we actually call setSorting...currently the only place is inside the resetSorting action. Personally I would move that action into the reducer and have resetSorting: () => { return initialState; }. So currently we don't even really need setSorting at all, though I can see how we might in the future, depending on what happens with PR #2376.

@lindapaiste @raclim I think the overall functionality works now, we are able to sort and search but one unit-test is getting failed, probably need to look at this one and update as early as possible
