Reload Match Events

Hi,
I have a 2 player PvP turnbased game with which I plan to save any match events to the cloud storage and then reload these events when a player leaves and rejoins the same match.

Within the MatchLoop function, I save the OpCode and Data as per below:

let matchLoop: nkruntime.MatchLoopFunction = function (context: nkruntime.Context, logger: nkruntime.Logger, nakama: nkruntime.Nakama, dispatcher: nkruntime.MatchDispatcher, tick: number, state: nkruntime.MatchState, messages: nkruntime.MatchMessage[]) {
    let gameState = state as GameState;

    for (let message of messages) {
        dispatcher.broadcastMessage(message.opCode, message.data, null, message.sender);

        var matchStateCode = message.opCode
        var matchStateData = message.data

        saveDispatchedCode(matchStateCode, context.matchId, context.userId);
        saveDispatchedData(matchStateData, context.matchId, context.userId);
        };
    return gameState.endMatch ? null : { state: gameState };
}

The SaveDispatchedCode & SaveDispatchedData functions are written as follows:

function saveDispatchedCode(code: number, matchID: string, userID: string) {

    var value = { code };

    var write: nkruntime.StorageWriteRequest = {
        key: "MatchStates",
        collection: "Codes",
        value: value,
        userId: userID,
        permissionRead: 1,
        permissionWrite: 0,
    }
}

function saveDispatchedData(data: ArrayBuffer, matchID: string, userID: string) {

    var value = { data };

    var write: nkruntime.StorageWriteRequest = {
        key: "MatchStates",
        collection: "Data",
        value: value,
        userId: userID,
        permissionRead: 1,
        permissionWrite: 0,
    }
}

No errors so far on the above, but I am struggling on how to write the code for reloading and broadcasting these match OpCodes and Data. This is what I have so far:

let reloadMatchState: nkruntime.RpcFunction = function (context: nkruntime.Context, logger: nkruntime.Logger, nakama: nkruntime.Nakama, dispatcher: nkruntime.MatchDispatcher, userID: string): string { 
    let storageReadCode: nkruntime.StorageReadRequest = {
        key: "MatchStates",
        collection: "Code",
        userId: userID,
    }
    let storageReadData: nkruntime.StorageReadRequest = {
        key: "MatchStates",
        collection: "Data",
        userId: userID,
    }

    let eventCode: nkruntime.StorageObject[] = nakama.storageRead([storageReadCode]);
    let eventData: nkruntime.StorageObject[] = nakama.storageRead([storageReadData]);

    for (let i = 0; i < eventCode.length; i++) {
        dispatcher.broadcastMessage(eventCode[i],eventData[i]);
    }

    logger.info("Receiving Event Code: " + eventCode + "and Event Data: " + eventData);
}

Regarding the ‘dispatcher.broadcastMessage(eventCode[i],eventData[i])’ code, I get the error: “StorageObject is not assignable to parameter of type ‘number’” which I understand because ‘eventCode[i]’ is meant to be a number and not a StorageObject.

Can you please provide any advice on how to convert a StorageObject to a number? Are there any examples of saving and reloading match events I can look at and is what I have written so far on the right track?

Any help would be appreciated.

Thanks
