Getting this error on AWS RDS with MS SQL

Database XXX cannot be restored because there is already an existing database with the same file_guids on the instance.

I've imported from S3 once, it worked. Deleted the database and tried to import a more recent version FULL DB and it broke.

I've created a new instance also but still get the error. I can import other DBs from S3 fine.

Anyone have any ideas that can help?

    I deleted all the instances and created a new one and it worked.

Ran into this issue last week. The issue was resolved on RDS.

It is possible to restore files with similar guids.

See tests and results in the attached pictures.
