VNext image not working with transactional batch

[trulsmp]

Describe the bug
Running transactional batch request returns 500 internal server error.

Is this part of known limitations and same as bulk execution? https://learn.microsoft.com/en-us/azure/cosmos-db/emulator-linux#limitations

To Reproduce

Example code used:

 var container = client.GetContainer("cosmosdb", "products");
 PartitionKey partitionKey = new("roadBikes");

var batch = container.CreateTransactionalBatch(partitionKey);

var bike = new Product
{
    id = "68719520766",
    category = "roadBikes",
};

batch.CreateItem(bike);

using TransactionalBatchResponse response = await batch.ExecuteAsync();

This gives error
DocumentClientException with status code InternalServerError, message: {"code":"InternalServerError","message":"invalid byte sequence for encoding \u0022UTF8\u0022: 0x81"}

Expected behavior
Items created in database as expected and response successful.

Desktop (please complete the following information):

• OS: Mac OS M2
• Version mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:vnext-preview
• SDK 3.47.0
• SDK .NET

Same issue if you run inserts in paralell with AllowBatchExecution = true.

I am hitting this issue when testing the preview Cosmos DB emulator with Orleans

Hi,

Thanks for bringing this issue to our notice.

The Batch request feature (both transactional and bulk-mode) on the V-Next emulator is currently not supported specifically with the .NET SDK (other SDKs like Java and Golang are supported). We are currently evaluating a path forward to implement this support for the .NET SDK as well.

Any update on this issues or timeline? This is currently blocking us from using the emulator and fixing it would greatly improve our development flow.
