@agriesser Thank you very much for your help. We have tried performing an import again after tinkering with the channels.jsonl and folder names of channels inside export file (.zip) generated from slack, due to a constraint which was causing an error when channel names start with a hyphen. After removing the hyphen at the start of channel names (both for folder names and channel names inside channels.json).
After performing all the steps for importing, we are getting the error log mentioned below. Does this mean that there is some sort of member limit for mattermost teams due to our mattermost edition?
