sco must be an instance of SCO

[andhwynm]

My TLS connection code encountered an error.（sco must be an instance of SCO）

conn_info = '%s(%s)' % (HOST, PORT)
cd = CD()
cd.SSLCipherSpec = TLS_CIPHER
sco=SCO()
sco.KeyRepository = KEY_REPOSITORY
queue_manager = mqqmgr.connect(QUEUE_MANAGER, CHANNEL, conn_info, USER_ID, API_KEY, cd=cd, sco=sco)

Commenting out the following code resolved the error.

ibmmq.mqqmgr.py L160-L162
if sco:
if not isinstance(sco, SCO):
raise TypeError("sco must be an instance of SCO")

Your connect line seems a bit confused. It's mixing explicit channel information with use of the MQCD structure. So that's probably not a good idea - either use the channel/conname or use the MQCD. Mixing the models might mean that not all of the parameters end up with what you might expect. And you've not shown how you've imported things so I can't see how sco=SCO() works at all, without a package qualifier such as sco = mq.SCO()

But assuming that the SCO really does resolve to the right thing, when I try your code, it seems to work fine.

Look at the connect_client_tls example for one way that works, using the underlying connect_with_options function.

Thank you for your answer. I understand the reason for the mistake.

import ibmmq as mq
...
cd = mq.CD()
sco = mq.SCO()
mq.connect(
mq.Queue(

There is one more question.
In PyCharm will generate warning messages, How to solve this problem.
Such as：
