Gen2 data flow + lakehouse + date = stop working

[Jerome22]

Hi,

I got mashup errors related to a date column between my Gen2 dataflow and a lakehouse.

my flow is working fine for weeks

and starting friday I start receiving mashup error related to my date columns. 

while nothing has changed.

my Gen2 DF apply a date tansformation and the lakehouse has a date destination column for weeks without any issue.

I finally solve this by dropping the table in my lakehouse, recreate them and using the date/time column format in the lakehouse table. (while my dataflow is still using a date transformation)

it's not the first time I have issues like that, with dataflow working and suddenly receiving mashup errors.

it's far from stable system if a simple mapping can't stay functionnal.
