Hi All,
Sometimes we are getting this nullpointer errors. Are there any suggestions about this error.
Thanks

@yadiguzel I just checked the code, and it looks like this is the code where we turn the key into a byte array.
Can you describe the workload you’re running? We need to track down a potential null key somewhere in your code. Maybe can you also share the code?
* @param nodes the managed nodes.
* @param config the bucket configuration.
* @return an observable with one or more nodes to send the request to.
*/
private Node[] locateForCouchbaseBucket(final BinaryRequest request, final Set<Node> nodes,
final CouchbaseBucketConfig config) {
String key = request.key();
CRC32 crc32 = new CRC32();
try {
crc32.update(key.getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
long rv = (crc32.getValue() >> 16) & 0x7fff;
int partitionId = (int) rv & config.numberOfPartitions() - 1;
request.partition((short) partitionId);
int nodeId;
if (request instanceof ReplicaGetRequest) {
nodeId = config.nodeIndexForReplica(partitionId, ((ReplicaGetRequest) request).replica() - 1);
@daschl here is my code in getWithCas method i can check whether is null or not. But this id is session id it can’t be null.
Our workload is not huge about 4000 req/s on each bucket in normal conditions. I could be up to 8K req/s.
object CouchbaseConnectionService extends Configuration with Logging {
val environment : CouchbaseEnvironment = DefaultCouchbaseEnvironment.builder().build()
def resolveBucket(name: String): Bucket = {
def query(q: ViewQuery, from: String): Future[ViewResult] = {
def getWithCas(from: String, id: String): Option[(JsonObject, Long)] = {val result = resolveBucket(from).get(id, 10, TimeUnit.SECONDS) //log.info (s"${id} loaded from ${from} with cas ${result.cas}")

@yadiguzel can you reproduce this in a development environment? It would be interesting to see what the request that it is trying to locate looks like - that would help a lot!
