Thank you for the quick response.

My CCD is the ZWO CCD ASI130MM.
I would set the BLOB mode to the following.
What do I set for the EMPTY argument? 1 or PyIndi.B_ALSO
indiclient.setBLOBMode(EMPTY, 'ZWO CCD ASI130MM', "CCD1")

Following the tutorial indilib.org/develop/indi-python-bindings.html :

I get the following error when taking an exposure:
