MongoDB Error: 16 Invalid Length when sharding a large collection

When sharding a large collection, I receive the following error message. Mongodb version 3.6 chunk sizes tried: 64, 128, 512, 1024 There is no more information than this in the error. How can I find out what is causing this?

    "ok" : 0,
    "errmsg" : "InvalidLength",
    "code" : 16,
    "codeName" : "InvalidLength",
    "operationTime" : Timestamp(1624108643, 8),
    "$clusterTime" : {
        "clusterTime" : Timestamp(1624108643, 53),
        "signature" : {
            "hash" : BinData(0,"WQ9ND4K0tw0iNbxnyoa9F9WzufM="),
            "keyId" : NumberLong("6948599486780276762")
        }
    }
}```
