Mongodb multilingual insertion ignores custom repeating field error

Question

I need to insert 3 recordsets from array 1 already exists, and 2 - new

eg:

db.products.insert(
   [
     { imagename: "pen1", qty: 21 },
     { imagename: "pen", qty: 20 },
     { imagename: "eraser", qty: 25 }
   ]
)

Where "{imagename:" pen ", qty: 20}" `already exists and has a unique key on the" imagename "field in mongodb

since now none of them gets up and throws err: "E11000 duplicates the key error index: mongotest.mothership. $ imagename_1 dup

any suggestion on how to insert the remaining two ignore errors into one go!

     { imagename: "pen", qty: 20 },
     { imagename: "eraser", qty: 25 }],
    { ordered: false }
)

: E11000 : mongotest.products: imagename_1 dup key: {: 'pen'}. . ... catche

try {
db.products.insert(
        [{ imagename: "pen", qty: 21 },
         { imagename: "pen", qty: 20 },
         { imagename: "eraser", qty: 25 }],
        { ordered: false }
    )
}catch(e){
print(e)
