Hello @ibrahimi3 can you provide more details to know exactly in what step of the process and what part of the channel you were trying to import when you got that error? That channel has 9971 resources and it would be hard to know if one of them is corrupted.
Also, it would be good if you can retry it and check if it works now, a temporary network issue might have been the reason for your problem too.
