      rs.initiate()
rs.add("172.26.251.51:27017")
rs.addArb("172.26.251.61:27017")  
rs.status()
      Show
      rs.initiate() rs.add( "172.26.251.51:27017" ) rs.addArb( "172.26.251.61:27017" ) rs.status()

      I have an installation of 3 MongoDBs which should act as a replica set, two of them data bearing nodes and one an arbiter. I have already configured both data bearing nodes but I have a problem configuring the arbiter.

      > rs.addArb("172.26.251.61:27017")
{
  ok: 1,
  '$clusterTime': {
    clusterTime: Timestamp({ t: 1663326365, i: 2 }),
    signature: {
      hash: Binary(Buffer.from("0000000000000000000000000000000000000000", "hex"), 0),
      keyId: Long("0")
    }
  },
  operationTime: Timestamp({ t: 1663326365, i: 2 })
}

      Then I check and I get an error:

      rs.status()
BSONError: Invalid UTF-8 string in BSON document

      If I remove the arbiter `rs.remove("172.26.251.61:27017")` then `rs.status()` works properly again:
