Problems with AWS DMS and MongoDB Atlas

0

I have a problem that I really don’t know how to solve or what approach to take. For data analysis and other similar things I need to use the AWS data migration service to migrate data from mongoDB to an AWS Redshift, but when I run the migration task I always get an error: “Unable to find transaction: …” . This process reads the oplog of the replica set. I have seen that this problem only occurs in certain collections not in all but I can’t find the possible cause. Any ideas?

You need to open an AWS Support case. Without looking at the logs it will be hard to debug what the issue is
