      ReadPreferences is only respected when included in the connection string. When configured programmatically, it's ignored.

      // Read preference is ignored
// Reads when no primary is present yields "(NotMasterNoSlaveOk) not master and slaveOk=false"
mongoConnString := "mongodb://mongo1,mongo2,mongo3/?replicaSet=rs0"
client, err := mongo.NewClientWithOptions(mongoConnString,
  options.Client().SetReadPreference(readpref.PrimaryPreferred()), 
)

       // Read preference is respected
mongoConnString := "mongodb://mongo1,mongo2,mongo3/?replicaSet=rs0&readPreference=primaryPreferred"
client, err := mongo.NewClientWithOptions(mongoConnString)
