Gen2 Dataflow can't create a new delta table in lakehouse

[viktor_bakayov]

Hi,

When I point a query to be saved as a new table in a Lakehouse, the creation is not successful with an error:

Mashup Exception Error Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: Error in replacing table's content with new data in a version: #{0}. Details: A000 GatewayObjectId: 58ba7394-1f76-449e-81a4-30571e2d245a

I notice the table is created with correct schema but with an empty content (no data inside). I am not using staging.

The data is consumed from an oracle source and few column type transormations are applied; The table and column names does not have any not allowed characters as desribed in the limitations documentation

Pointing it to an existing table with the same shema works just fine
