Allow Null value for covertimezone expression

[picnicfunL]

My purpose: add a convertimezone expression in my flow and also allow the user to leave as blank

My problem: if users leave date as blank, the flow will fail as below:

Hi there!  Are you using the date later in the Flow?  Wondering if you can just use UTCNow() if it is blank, and then just ignore the output of this step later?

Just a thought.

Yes, I need the time for email, also the time is not "now" so I am not able to use UTCnow()

[edgonzales]

So, If it's required, what is your intent if the user leaves it blank?

[picnicfunL]

It depends on the situation, at the begin, users don't know the correct time, they will fill out the time when the event is restored. 

Now I add condition " time is equal to ture"

It might help if you can chart out what the journey should look like, right?  It sounds like there is information required before the user actually has it, in some cases.  If that's the case, it might be necessary to plug in a 'sample' value to move forward, and then update it later.

Keep us posted.

Hi @picnicfunL ,

You could try to use the If() function to determine if the Date field value is empty and if so, do nothing. If it is not empty, execute the convertTimeZone() function.

Expression reference:

if(equals(triggerBody()?['Date'],null),'',convertTimeZone(triggerBody()?['Date'],'Dateline Standard Time','Central Standard Time','yyyy-MM-dd'))

Best Regards,
