tables with a nonclustered primary key are not supported on Microsoft Fabric platform

[lkara777]

I mirror data from an azure sql db to Fabric, but before azure sql db, we replicate data from an old db in a azure managed instance to azure sql db and then we mirror to Fabric. In the old db some tables have constraints, non clustered keys but in the azure sql db we do not copy those constraints only keep primary keys. But yesterday after recreate the replication, we had this error and I do not understand why, and also for those tables we have data in the Fabric but 1 day behind. Do you know why?
