print(type(current))

This code results in the following error:

I know that this probably doesn't have anything to do with this library since it is an SynologyDSMAPIErrorException, but I wasn't sure what to do from here. Am I using the wrong ID for each camera? When I logged into the interface in my browser, I saw the camera identifier followed by a hyphen and the name of the camera. I used those identifiers in this script.

I was skimming through some random PDF I found on Google and looked at page 274 and compared what I saw to the code for the capture_camera_image method. I noticed that the method code does not use the dsId field. I don't think this is why there is a problem, but I thought I would share anyway.
