How to format stream_id for get_stream_info() call

[jlixfeld]

Hi Oliver,

I'm so grateful for the hard work that you've put into your Unicorn Binance suite! I'm working on migrated over to it from Sam McHardy's API.

From IPython, I can call print_summary() and get a stream_id, but when I try to call get_stream_info() using the UUID I get False returned. I'm not sure what I'm doing wrong in formatting that call. Do you have any tips?

Thanks!

Thank you :)

I think the problem is that you provide the stream_id in string format!

Just wrap it in UUID() as returned from get_stream_id_by_label():

ubwam.get_stream_info(UUID('24e798fe-0b9e-4e7b-9802-efc3a36b2830'))!

I tried that previously as well, with no success:

do import uuid before!

Really weird. This doesn't work:

But this does work...
