.to_date problem

Hey there. I am adding 2 days to a date field. When I put in the formula

field(‘Date Received’) + days(2).to_date

it gives me the correct output, but it has a utc timestamp on it

based on the question here-

I should add .to_date to the formula to remove the time stamp. When I add .to_date it gives me an error of

error: Could not access blank value: Use || to provide a default value for blank fields. Example: (my_field || 0) + 1

I have been playing with this since yesterday and I figured I would see if someone that knows more than I do can help me out.

Thanks
