I'm trying to migrate from Magento 1 to 2 and when I get to this part:
[2017-10-06 14:04:36][INFO][mode: data][stage: data migration][step: Map Step]: started 33% [=========>------------------] Remaining Time: 3 mins
I then get this error
[PDOException]
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '0' for key 'PRIMARY'
Any ideas?
