我正在嘗試使用以下代碼在新集合中插入更多檔案：
await client.db(db).collection(newCollection).insertOne(newDocument);
但是，這會遇到錯誤代碼 8000，此處未記錄：https ://github.com/mongodb/mongo/blob/master/src/mongo/base/error_codes.yml 。

我做了進一步的研究，發現一個創建的集合數量不受用戶限制（“一般來說，盡量將你的副本集限制為 10,000 個集合”），如下所述：https: //www.mongodb.com/developer/ products/mongodb/schema-design-anti-pattern-massive-number-collections/#:~:text=In general, try to limit your replica set to 10,000 collections。
我在共享集群上使用 Atlas。這是 Atlas 問題還是我的代碼有問題？
uj5u.com熱心網友回復：
是的，這是atlas M0免費限制。看Database and Collections 這里
