Hi Mads,
I see that the problem is with the amount of users on your account. There are too many of them so the Asana’s API does not want to return such a big list.
I am not sure I can do anything to fix this. We need this user’s list to display assignee names in the exported csv.
The best would be to get info about that error from somebody from Asana’s API. Is it possible to get such a big list of users?
Another solution would be to export report without usernames but this is what I would like to avoid.
Best regards,
