unknown format error - Githubissues

Hi I'm using host-sflow will the following config: pcap { dev = docker_gwbridge }

My js code has this: Collector(function(flow) { if (flow && flow.flow.records && flow.flow.records.length>0) { flow.flow.records.forEach(function(n) { console.log(n); }); } }).listen(6343);

After a few flows, it consistently fails with "unknown format" err. Following is out with debug turned on:

Any idea what is happening here?
