Durable Functions work correctly locally, but not when deployed?

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

Introduction of the 'standard' sample durable function code (SayHello , which calls activities to say hello for Tokyo , London and Seattle) works fine locally with either a AzureStorage provided as the HostStorage OR with an environment variable for AzureWebJobStorage being provided (which references an existing Azure storage container).

However, when deployed using the inbuilt deploy option within Visual Studio, neither the solution which references the AzureStorage or the existing storage via the environment variable works.

With the environment variable, the azure functions project does startup when deployed, and non durable functions can be successfully invoked, but upon first invocation of a http endpoint which is used to instigate a durable orchestration, one gets an exception.

### Expected Behavior

To function as it does when executed locally.

### Steps To Reproduce

Take an existing minimal functional Aspire Azure Functions project.

Add the existing sample durable SayHello function code to it.

```
using Microsoft.Azure.Functions.Worker;
using Microsoft.Azure.Functions.Worker.Http;
using Microsoft.DurableTask;
using Microsoft.DurableTask.Client;
using Microsoft.Extensions.Logging;

namespace FunctionApp2
{
public static class Function
{
[Function(nameof(Function))]
public static async Task> RunOrchestrator(
[OrchestrationTrigger] TaskOrchestrationContext context)
{
ILogger logger = context.CreateReplaySafeLogger(nameof(Function));
logger.LogInformation("Saying hello.");
var outputs = new List();

// Replace name and input with values relevant for your Durable Functions Activity
outputs.Add(await context.CallActivityAsync(nameof(SayHello), "Tokyo"));
outputs.Add(await context.CallActivityAsync(nameof(SayHello), "Seattle"));
outputs.Add(await context.CallActivityAsync(nameof(SayHello), "London"));

// returns ["Hello Tokyo!", "Hello Seattle!", "Hello London!"]
return outputs;
}

[Function(nameof(SayHello))]
public static string SayHello([ActivityTrigger] string name, FunctionContext executionContext)
{
ILogger logger = executionContext.GetLogger("SayHello");
logger.LogInformation("Saying hello to {name}.", name);
return $"Hello {name}!";
}

[Function("Function_HttpStart")]
public static async Task HttpStart(
[HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")] HttpRequestData req,
[DurableClient] DurableTaskClient client,
FunctionContext executionContext)
{
ILogger logger = executionContext.GetLogger("Function_HttpStart");

// Function input comes from the request content.
string instanceId = await client.ScheduleNewOrchestrationInstanceAsync(
nameof(Function));

logger.LogInformation("Started orchestration with ID = '{instanceId}'.", instanceId);

// Returns an HTTP 202 response with an instance management payload.
// See https://learn.microsoft.com/azure/azure-functions/durable/durable-functions-http-api#start-orchestration
return await client.CreateCheckStatusResponseAsync(req, instanceId);
}
}
}
```
Add a call to

`builder.ConfigureDurableExtension();`

Publish aspire solution, and attempt to invoke the function api/Function_HttpStart

Observe contents of log.

### Exceptions (if any)

When just running with the added azure storage this exception is seen

When ran with an environment variable for the storage specified (and also now specified in the hosts.json file in the extensions section) , one gets this :
