Error when inserting Documents with for Loop

Question

When I try to add some Documents to a Collection, exactly 1 of 4 times I get an Error.

for (var i = 0; i < 50; i=i+1){
    db.SampleOrder.insert(
    {
        "SampleId": NumberInt(i),
        "PuckId": NumberInt(i)
    });  
}

Error: Picture of the Error

Does anybody know why this doesn't work? I use Robomongo Robo 3T 1.1.1.

Answer 1

you can use insertMany instead of insert to insert multiple document

like:

var docs = [];
for (var i = 0; i < 50; i=i+1){
    docs.push({
        "SampleId": NumberInt(i),
        "PuckId": NumberInt(i)
        });
}
db.SampleOrder.insertMany(docs);
