Hi all,
I am testing some courses to export from Blackboard and import into Canvas.
I keep getting the mysterious error displayed below.

I am working through different modules to try and figure out what is causing the problem and so far think it is the advanced adaptive release rules I have set up in the module on Blackboard (BB). To clarify, one of these rules only permits members of a specific group to view a content folder in BB, all other users are not able to view it. These rules are displayed in BB as shown in the screenshot below:

Will try and remove these shortly and update but that's what I think is causing it.
Any other insights would be appreciated!
Thanks,
Steve
