node.js - ReplicaSetNoPrimary MongooseServerSelectionError: getaddrinfo EAI_AGAIN mongodb-primary

Question

我已经在 docker 中设置了一个 mongodb 副本集。当我使用 cli 连接到 mongodb 时，它工作正常。但是，尝试使用 mongoose 包通过 node.js 连接到它会给出以下错误消息。

MongooseServerSelectionError: getaddrinfo EAI_AGAIN mongodb-primary at NativeConnection.Connection.openUri (/home/kay/checkpoint/stream-hatchet/node_modules/mongoose/lib/connection.js:800:32) at /home/kay/checkpoint/stream-hatchet /node_modules/mongoose/lib/index.js:341:10 at /home/kay/checkpoint/stream-hatchet/node_modules/mongoose/lib/helpers/promiseOrCallback.js:31:5 at new Promise () at promiseOrCallback (/ home/kay/checkpoint/stream-hatchet/node_modules/mongoose/lib/helpers/promiseOrCallback.js:30:10) 在 Mongoose.connect (/home/kay/checkpoint/stream-hatchet/node_modules/mongoose/lib/index. js:340:10) 在 Object.MongoDBService [默认] (/home/kay/checkpoint/stream-hatchet/src/services/mongodb.service.ts:20:24) 在 Streaming (/home/kay/checkpoint/ stream-hatchet/src/main.ts:16:29) 在对象。(/home/kay/checkpoint/stream-hatchet/src/main.ts:38: 1) 在 Module._compile (internal/modules/cjs/loader.js:1137:30) 在 Module.m._compile (/home/kay/checkpoint/stream-hatchet/node_modules/ts-node/src/index.ts :858:23) 在 Module._extensions..js (internal/modules/cjs/loader.js:1157:10) 在 Object.require.extensions。[as .ts] (/home/kay/checkpoint/stream-hatchet/node_modules/ts-node/src/index.ts:861:12) 在 Module.load (internal/modules/cjs/loader.js:985: 32) 在 Function.Module._load (internal/modules/cjs/loader.js:878:14) 在 Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:71:12) {原因：TopologyDescription { type : 'ReplicaSetNoPrimary', setName: 'replicaset', maxSetVersion: 61323, maxElectionId: 7fffffff0000000000000002, 服务器: Map {'mongodb-primary:27017' => [ServerDescription], 'mongodb-arbiter:27017' => [ServerDescription] },陈旧：

import mongoose from "mongoose";
