aerospike-client-go: PARAMETER_ERROR using expressions and batch write

Trying to implement conditional update via expressions using versioning for records. BatchOperate doesn’t return any error, but the data is not written to aerospike.

UPD: i’ve noticed that the record has ResultCode: PARAMETER_ERROR inside after the BatchOperate is called.

Is it not possible to do batch writes with expressions? Or maybe there should be some better error? Removing the filter expression makes the record being written. Chaning filter expression to any other doesn’t help as well. Here’s the example of code i’m using

acc := Account{
	Pubkey: 	"test123",
	Data:       []byte{1, 2, 3},
	Version:	1,
}

key, err := aero.NewKey(namespace, set, acc.Pubkey)
if err != nil {
	return err
}

// Create the policy
writePolicy := aero.NewBatchWritePolicy()
writePolicy.FilterExpression = aero.ExpLess(aero.ExpIntBin(binVersion), aero.ExpIntVal(acc.Version))

// Create write operation
record := aero.NewBatchWrite(writePolicy, key,
	aero.PutOp(aero.NewBin(binData, acc.Data)),
	aero.PutOp(aero.NewBin(binVersion, acc.Version)),
)

records := []aero.BatchRecordIfc{record}
err := s.conn.BatchOperate(nil, records)

fmt.Println(err, records)

The result is: nil, [Key test:accounts:test123:d1 02 ed d3 9d bd 5b a9 7e 97 e2 45 8f b6 15 49 54 40 e6 d1 , Record: <nil>, ResultCode: PARAMETER_ERROR, InDoubt: false, Err: <nil>]

The setup i’m using:

• ubuntu 20.04
• aerospike-server-community 6.2.0.3
• golang 1.19
• aerspike-client v6@v6.10.0

Thanks
