Data Refresh Errors

i am very new to Fabric. i have a dataflow setup, with a semantic model and report which all works, however i am getting the following error on a dataflow gen2 scheduled refresh. The destination for the data is in Lakehouse. My only fix a the minute is to delete the table out of the Lakhouse and then it recreates automatically but subsequent refreshes fail.

Private data below replaced with xxxxxxxxxxxxxxxx

any help appreciated. i have tried deleting the tables and recreating but every refresh fails.
