How to pass object from trigger to orchestra and activity functions

Question

I have HTTP trigger which invokes orchestra function. In HTTP trigger function I receive json string which I deserialize into object . However I have no idea how to pass this object to orchestra function or activity functions.

I have tried to include it as parameter of orchestra function but it gives me error

HTTP trigger

#load "../Shared/jsonObject.csx"
public static async Task<HttpResponseMessage> Run(
HttpRequestMessage req,
DurableOrchestrationClient starter,
string functionName,
ILogger log)
{

HttpContent requestContent = req.Content;
string jsonContent = requestContent.ReadAsStringAsync().Result;
jsonObject bsObj = JsonConvert.DeserializeObject<jsonObject>      (jsonContent);  

// Pass the function name as part of the route 
string instanceId = await starter.StartNewAsync("Orchestra", bsObj);

log.LogInformation($"Started orchestration with ID = '{instanceId}'.");

return starter.CreateCheckStatusResponse(req, instanceId);
}

Orchestra function

#load "../Shared/jsonObject.csx"
[FunctionName("Orchestra")]
public static async void Run(DurableOrchestrationContext context)
{   

var output = await context.CallActivityAsync<int>("checkConditions", bsObj);
}

Activity functionn not implemented yet

#load "../Shared/jsonObject.csx"
public static string Run(jsonObject bsObj)
{
return  "done";

}

[Error] run.csx(19,74): error CS0103: The name 'bsObj' does not exist in the current context

Please try running the below code

HTTP Trigger function.

    [FunctionName("HttpTriggerCSharp")]
    public static async Task<HttpResponseMessage> Run(
        [HttpTrigger(AuthorizationLevel.Function, "post")]HttpRequestMessage req,
        [OrchestrationClient]DurableOrchestrationClient starter,
        ILogger log)`
    {

        HttpContent requestContent = req.Content;
        string jsonContent = requestContent.ReadAsStringAsync().Result;
        JObject bsObj = JsonConvert.DeserializeObject<JObject>(jsonContent);
        // Pass the function name as part of the route 
        string instanceId = await starter.StartNewAsync("Orchestra", bsObj);
        log.LogInformation($"Started orchestration with ID = '{instanceId}'.");
        return starter.CreateCheckStatusResponse(req, instanceId);
    }

Orchestration Function

        [FunctionName("Orchestra")]
    public static async Task RunOrchestrator(
        [OrchestrationTrigger] DurableOrchestrationContext context)
    {
        var bsObj = context.GetInput<JObject>();
        var output = await context.CallActivityAsync<JObject>("checkConditions", bsObj);
    }    

Activity Function

        [FunctionName("checkConditions")]
    public static string SayHello([ActivityTrigger] JObject bsObj, ILogger log)
    {
        //Assign input value to any variable
        var json = bsObj;
        //Logic of the code
        return "done";
    }    

I have referenced this doc for durable functions extention and this doc for HTTP Triggered functions.
