Mongocxx library segmentation fault

I'm trying to install the mongo-c-driver and mongo-cxx-driver in a Docker image, but when I run my C++ program it throws a Segmentation fault. Any ideas? Valgrind says it's mongo's fault.

I have some IOT devices and in my own computer they run just fine.

I'm using:

  • ubuntu:focal as base image
  • mongo-c-driver version 1.16.2 (also tried with 1.17 and 1.15)
  • mongo-cxx-driver version 3.5 (also tried with 3.6)
  • MongoDB server version 4.2.8
  • g++ version (Ubuntu 9.3.0-10ubuntu2) 9.3.0

Code:

std::string MongoDB::insertDocument(std::string database,
    std::string collection, bsoncxx::document::view_or_value document)
{
    try
    {
        mongocxx::uri uri(_connection_string);
        mongocxx::client conn(uri); // seg fault occurs here

        mongocxx::database db = conn[database];
        mongocxx::collection coll = db[collection];

        auto inserted = coll.insert_one(document.view());

        bsoncxx::oid oid = inserted->inserted_id().get_oid().value;
        return oid.to_string();
    }
    catch (const mongocxx::exception & e)
    {
        std::cerr << "WARNING: Unable to connect to MongoDB" << std::endl;
        return "UNKNOWN";
    }
}

Variable values:

_connection_string = "mongodb://burns"
database = "hopping"
collection = "executions"
document = 
{
    "created_at" : "2020.09.29 10:48:51",
    "hostname" : "XXXXX",
    "interface" : "wlp3s0mon",
    "schedule" : [ 1 ],
    "slot_size" : 200,
    "type" : "MOCK_NODE"
}

Ps: mock_node is my executable and influxdb-logging is a library of mine.

Thank you very much, I have no idea what could be causing this...
