Hi Team,
The customer is running the below script to initialize collections and indexes and is getting the error
MongoError: not master
The script is
const client = await MongoClient.connect(this.mongoConfig.url(), { useNewUrlParser: true, ignoreUndefined: true, useUnifiedTopology: true, readPreference: ReadPreference.SECONDARY_PREFERRED, }); getCollection(name: string): Collection { // Prioritize safety over speed // Ensures enough nodes have really written the data. // Set default write concern to majority, wait for journal to be written and set a write timeout instead of infinite. const options: DbCollectionOptions = { w: "majority", j: true, wtimeout: 5000, }; return this.database.collection(name, options, (error, collection) => { if (error) { throw error; } return collection; }); }
- MongoDB Driver:node-mongodb-native v3.6.0
- Cluster - opus
- The connection string used is the SRV string.
I asked the customer to remove the readPreference: ReadPreference.SECONDARY_PREFERRED, but they insisted that it works on other cluster in different projects so they cannot change it.
