Bug Report

YDB GO SDK version:
3.74.3

Environment
MacOS Sonoma 14.2.1 AMD64

Current behavior:

2024/06/18 13:06:47 queryconnError{node_id:1,address:'localhost:2136'}: operation/NOT_FOUND (code = 400140, address = localhost:2136, issues = [{#2015 'Transaction not found: '}]) at `github.com/ydb-platform/ydb-go-sdk/v3/internal/conn.(*grpcClientStream).RecvMsg(grpc_client_stream.go:178)` at `github.com/ydb-platform/ydb-go-sdk/v3/internal/query.nextPart(result.go:143)` at `github.com/ydb-platform/ydb-go-sdk/v3/internal/query.newResult(result.go:101)` at `github.com/ydb-platform/ydb-go-sdk/v3/internal/query.execute(execute_query.go:74)` at `github.com/ydb-platform/ydb-go-sdk/v3/internal/query.transaction.Execute(transaction.go:83)`

Expected behavior:
No error, 42 in stdout.

Steps to reproduce:
Run the code.

Related code:

package main

import (
	"context"
	"errors"
	"fmt"
	"io"
	"log"
	"time"

	"github.com/ydb-platform/ydb-go-sdk/v3"
	"github.com/ydb-platform/ydb-go-sdk/v3/query"
)

func main() {
	ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
	defer cancel()

	driver, err := ydb.Open(ctx, "grpc://localhost:2136/local")
	if err != nil {
		log.Fatal("open", err)
	}
	defer driver.Close(ctx)

	err = driver.Query().DoTx(ctx, func(ctx context.Context, s query.TxActor) error {
		res, err := s.Execute(ctx, `SELECT CAST(42 AS Uint32);`)
		if err != nil {
			log.Fatal("query", err)
		}

		var a uint32
		for set, err := res.NextResultSet(ctx); !errors.Is(err, io.EOF); set, err = res.NextResultSet(ctx) {
			if err != nil {
				return err
			}
			for row, err := set.NextRow(ctx); !errors.Is(err, io.EOF); row, err = set.NextRow(ctx) {
				if err != nil {
					return err
				}

				err = row.Scan(&a)
				if err != nil {
					return err
				}

				fmt.Println(a)
			}
		}
		return res.Err()
	}, query.WithIdempotent(), query.WithTxSettings(query.TxSettings(query.WithOnlineReadOnly())))

	if err != nil {
		log.Fatal(err)
	}
}

Other information:
There's no error if I remove query.WithTxSettings(query.TxSettings(query.WithOnlineReadOnly())).

Ydb_Query.BeginTransactionResponse=status:BAD_REQUEST issues:{message:"Failed to begin transaction: open transactions not supported for transaction mode OnlineReadOnly, use tx_control field in ExecuteDataQueryRequest to begin transaction with this mode.

[neyguvj]

Currently only two transaction modes are supported for interactive transactions:

• Snapshot Read-Only
• Serializable
