InvalidQueryException: Key may not be empty When using the Java Driver for DataStax Astra Cassandra DB.
I'm 100% sure that my partitionKey or my clusteringColumns are not empty. Can someone tell me what this error can mean besides that?
The same code worked 1 hour before what does that exception mean?
Thank you guys but I just found it myself.
I wrote a
Long
into anByteBuffer
and didn't useflip()
afterwards.
