ForbiddenApi error when calling a handler

We are getting this ForbiddenApi error when calling a handler from another handler.

public static dispatchFunctionInstant(server: IPlayFabServerAPI): any {
    // some things left out, parameters etc
    // invoke function
    const executeResult = server.ExecuteCloudScript({
        PlayFabId: player.PlayFabId,
        FunctionName: "_dispatchFunction",
        FunctionParameter: parameters,
        GeneratePlayStreamEvent: Configuration.ShouldGeneratePlayStreamEvents,
        RevisionSelection: "Specific",
        SpecificRevision: script.revision
    });
}

Error in playfab logs.

{
    "Message": "PlayFab API request failure",
    "Level": "Error",
    "Data": {
        "request": {
            "FunctionName": "_dispatchFunction",
            "GeneratePlayStreamEvent": true,
            "PlayFabId": "DDC6A9EB63D83764",
            "RevisionSelection": "Specific",
            "FunctionParameter": {
                "param1": "val1",
                "param2": {
                    "val2": "etc."
                },
            },
            "SpecificRevision": 8
        },
        "error": "ForbiddenApi",
        "api": "/Server/ExecuteCloudScript"
    }
}

"stack": "Error\n at Object.server_request (Script:162:24)\n at Object.server.ExecuteCloudScript (Script:518:75)\n at CounterServerAPIProxy.InvokeRequest (C6805-all:2618:16)\n at CounterServerAPIProxy.ExecuteCloudScript (C6805-all:2264:21)\n at Function.dispatchFunctionInstant (C6805-all:1405:38)\n at LocalPlayer.dispatchFunctionInstant (C6805-all:1359:23)\n at Function.checkRollActions (C6805-all:1605:23)\n at C6805-all:1585:43\n at Array.forEach (<anonymous>)\n at Function.checkRollsActions (C6805-all:1584:17)"

This has seemed to work before. Has something changed in permissions required, how to fix?

You should implement your function in a single handler. Calling server.ExecuteCloudScript in a CloudScript handler is not support, not only is this inefficient for the customer, it also ties up multiple JavaScript engines, affecting our cost and other customers' experience. If the CloudScript cannot meet your requirement, we recommend that you can use Azure Function which is more powerful and flexible.

Thanks for the recommendation. Did something change when it comes to calling server.ExecuteCloudScript in a CloudScript handler? I think it was possible before.

Yes, a change was recently applied, calling server.ExecuteCloudScript in a CloudScript handler is not allowed now.

Feel free to provide more information about your scenario because usually it is unnecessary to execute Cloud Script inside a Cloud Script function.
