Using an expression to create a due date in an email body

[MattJ]

Hi All, 

Scheduled flow to get items and then send the following email

tried using the following expression to create a due date based on column in the email, keeps throwing the following error

Any help on this would be appreciated

thanks 

Matt

Hi @MattJ 

The issue is with your formula. I can see you have an "if," but you probably have an addDays function inside. The first parameter that you're providing is empty. Please check what parameter it is and check in the Flow's run if it's really empty? If so, I would recommend another "if" statement to ensure that the addData always has s value.

Cheers

Hi Manuel, 

the expression is 

if(empty(item()?['LCSIIexpiry']),'no value', adddays(triggerBody()?['LCSIIexpiry'],-90,'yyyy-MM-dd'))

what do i need to change?

thanks for the quick response

Hi @MattJ 

Your reasoning is correct, but check if it's empty if it's empty, it will return false in case of null. 

Try matching like this:

if(equals(item()?['LCSIIexpiry'],null),'no value',addDays(item()?['LCSIIexpiry'],-90,'yyyy-MM-dd'))

If you still want to check for empty, include your iff statement in the "addDays" part of the expression above, and you'll have a formula that can test both.

Hi Manuel, 

thanks so much, so if the expression checking to see if column value is null, assigning no value if true, otherwise taking away 90 days?
