@UlyanaAndrukhiv this is just a note not to forget to include this PR to #6802, or should @AndriiDiachuk make changes in this PR?

[UlyanaAndrukhiv]

@Guitarheroua, yes responses will be included in #6802.

[Guitarheroua]

we should return results one by one, not as an array, check handler.go implementation as an example:

flow-go/access/handler.go

Lines 1435 to 1454 in 941178d

	messageIndex := counters.NewMonotonousCounter(0)
	return subscription.HandleRPCSubscription(sub, func(txResults []*TransactionResult) error {
	for i := range txResults {
	index := messageIndex.Value()
	if ok := messageIndex.Set(index + 1); !ok {
	return status.Errorf(codes.Internal, "message index already incremented to %d", messageIndex.Value())
	}
	err = stream.Send(&access.SendAndSubscribeTransactionStatusesResponse{
	TransactionResults: TransactionResultToMessage(txResults[i]),
	MessageIndex: index,
	})
	if err != nil {
	return rpc.ConvertError(err, "could not send response", codes.Internal)
	}
	}
	return nil
	})

The same should be done for TransactionStatusesDataProvider

Suggested change

	TransactionResults []*access.TransactionResult `json:"transaction_results"`
	TransactionResult *access.TransactionResult `json:"transaction_result"`
