mongodb uses BSON type.
if the driver of mongodb returns boolean data type then i can not detect in php. (not found or found).

for example
a document of MyCollection

{
    _id : "5f61f7ec0ec7a41c618477bf",
    myField : false
}

$value =
    MyCollection::Find()
        ->Select(['myField'])
        ->Where(['_id' => new MongoDB\BSON\ObjectId('5f61f7ec0ec7a41c618477bf')])
    ->Scalar()
;
yii::info($value,'test'); //now result found or not found ?

fix

if(
    MyCollection::Find()
        ->Select(['myField'])
        ->Where(['_id' => new MongoDB\BSON\ObjectId('5f61f7ec0ec7a41c618477bf')])
    ->Scalar($value)
){
    echo 'result found';
    //now you can use $value
}
else
    echo 'result not found';
