Image / file attachments all fail - Slack import

I have mattermost 5.9.0

I get a million messages like this when importing from Slack – and no image attachments in the channels:

{“level”:“warn”,“ts”:1560283469.4840775,“caller”:“app/slackimport.go:404”,“msg”:“Slack Import: Unable to attach the file to the post as the latter has no file section present in Slack export.”}

Hi @MrBryan, were you using the Slack Advanced Exporter tool?

A-ha – no but reading about it on github now… thank you!
