I'm trying to dump the protobuf message object using MessageToJsonString()
function
but encountering an exception. Sample code is as below followed by the
output without try{}catch()
ResultRecord* GetSampleData()
{
auto resultRecord = std::make_unique<ResultRecord>();
....
//Filling resultRecord
....
return resultRecord.release();
}
int main(int, char**) {
//Getting RecordData through Protobuf
auto data = GetSampleData();
if(data){
std::string str;
google::protobuf::util::JsonOptions opts;
opts.add_whitespace = true;
try{
google::protobuf::util::MessageToJsonString(*(data), &str, opts);
}
catch(std::exception e)
{
std::cout<< e.what()<<std::endl;
}
std::cout<<str<<std::endl;
}
return 0;
}
Output :
terminate called after throwing an instance of 'std::system_error'
what(): Unknown error -1
I'm not sure what to do to debug this. Can someone point me in right
direction ?
