3 years ago Hi. Could you provide an example message payload for this?
const payload = JSON.parse(msg.data);
const message = payload.data;For example, orderbook's message (i.e. msg.data) object is in the form of the following. It does not have another data property inside. So it makes more sense to be const message = JSON.parse(msg.data);.
{
e: 'depthUpdate',
E: 1635212586209,
s: 'BTCUSDT',
U: 14590880624,
u: 14590880705,
b: [
[ '62797.02000000', '0.66271000' ],
[ '62795.33000000', '0.00000000' ],
...
[ '62557.12000000', '0.00032000' ]
],
a: [
[ '62797.03000000', '2.18598000' ],
[ '62799.25000000', '0.00000000' ],
...
[ '64717.23000000', '0.00000000' ]
]
}Also, thanks for suggestion. Error message unknown method is easier to understand. We will refactor the method a bit and apply the change accordingly.

src/lib/socketClient.js line 38: const message = JSON.parse(msg.data);
returns the whole message payload, not the data part of the payload. So when you run it, on each message received you get an “Unprocessed method” error. It should be something like:
const payload = JSON.parse(msg.data); const message = payload.data;
I also suggest to change the error message text on line 48 to “Unknown method” to distinguish it from the message on line 45.
Best, Peter
