Dataflow is creating complex type column in Lakehouse tables from Decimal or Currency type

[christianunr]

Hello, I have a Dataflow that has been working pretty well over the past several weeks but today, after running it this morning, any column across six different tables have changed their type to complex in the Lakehouse on Fabric.

I've tried to delete the tables and create a new one from the Dataflow but the same complex type keeps appearing for these columns that are changed as a step in the Dataflow to decimal or curreny. (both transform to a complex type).

I haven't seen this before and not sure what is going on.
