Question regarding sending a Uint8Array

[xgdgsc]

I' m trying to use zeromq.js to send a flatbuffers buffer to a python process, like the tutorial

......
var buf = builder.asUint8Array()
this.pubSock.send(['ChannelName', buf])

I get error like:

struct.error: unpack_from requires a buffer of at least 4 bytes

when unpacking in Python. I' m not sure if it is the problem of the js side or python side. I want to ask would sending a Uint8Array like this work?

The latest 6.0 beta release supports Uint8Array messages. It would be great if you could try it out! The new version has a new API that addresses some fundamental issues with the previous API, but it does include a compatibility layer that should make upgrading easier. See #189 for the reasoning behind the new API. If you run into any problems feel free to report it here or in a new issue.
