I see that error when try to import manually edited members (batch process):
id email name subscribed_to_emails complimentary_plan created_at labels
621d387d2fe56c1597d0a34d e@mail.com name true false 2021-08-12T03:00:00.000Z Cool-label
What can be causing it? I need to remove all the members and try to import on clean way?
I had this exact problem, and it brought down my entire system.
I tried zeroing out the members table, but that made no difference. How did you solve the problem?
