Janusgraph server complains Websocket Max frame length of 65536 has been exceeded

I'm trying to load huge batch of data to janusgraph via a websocket connection from a go program.

Consistently I see this error. Is there a configuration property on the janusgraph to increase this size?

1761394 [gremlin-server-worker-1] WARN  io.netty.channel.DefaultChannelPipeline  - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.

It is very well explained in this stackoverflow answer Max frame length of 65536 has been exceeded

Currently, my janusgraph server uses /etc/opt/janusgraph.janusgraph-server.yaml. maxContentLength by default is 65536. Setting it to higher values solves the issue.

host: 0.0.0.0
port: 8182
evaluationTimeout: 30000
channelizer: org.apache.tinkerpop.gremlin.server.channel.WsAndHttpChannelizer
graphs:
  graph: /etc/opt/janusgraph/janusgraph.properties
scriptEngines:
.

.
maxInitialLineLength: 4096
maxHeaderSize: 8192
maxChunkSize: 8192
maxContentLength: 655360
maxAccumulationBufferComponents: 1024
resultIterationBatchSize: 64
writeBufferLowWaterMark: 32768
writeBufferHighWaterMark: 65536
