v0_8 starknet_traceBlockTransactions not working

[GMKrieger]

When calling the starknet_traceBlockTransactions endpoint using rpc version 0_8, it returns this error:

Failed to get block tx traces: Other(TransportError(Json(Error("data did not match any variant of untagged enum JsonRpcResponse", line: 0, column: 0))))

When trying to run the tests, updating the serialize version from 07 to 08 on test_multiple_transactions made the test fail.

Hey @GMKrieger, I haven't been able to reproduce any errors on this method.

Could you please share your RPC query with us?

Here's an example of a usable format:

POST http://127.0.0.1:9545/rpc/v0_8 HTTP/1.1
Content-Type: application/json

{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "starknet_traceBlockTransactions",
    "params": {
        "block_id": "latest"
    }
}
