"Container is less than required fields number. Deserialization failed" error #252

Open cooked opened 3 years ago

cooked commented 3 years ago

Hi, I'm getting the following error while I'm trying to deserialize a proto containing a repeated value

terminate called after throwing an instance of 'std::out_of_range'
  what():  Container is less than required fields number. Deserialization failed

The application is running fine for 20-30 seconds, correctly deserializing messages, then the error occurs.

I confirmed that the proto is the same used to generate code on both ends (Qt and C++)

message Telemetry {
  Chip chip = 1;
  Channel channel = 2;
  repeated int32 value = 3;
}

What is the workflow, and points to look into, to find the root cause of the issue?

Thanks, Stef

Looks like bug to me. If you could run your application in debug mode and send the stack trace(at least QtProtobuf related part), I would appreciate.
