how to update date format for a date field if not null in select action

[dmistry]

Hi,

I am using flow select action under which I have a field called 'completiondate' that is populated for some rows in sp list and not for some rows. So it works well but now I have a requirement to update the date format to mm/dd/yyyy so when using formatdatetime(item()?['CompletionDate'],'MM/dd/yyyy') as expression , it fails and says supplied value were null and it makes sense because some rows do not have completiondate populated.

can someone help me with a fix here, so if date is returned null then leave it null, if populated then update it with format mm/dd/yyyy for select action expression, please help, thanks in advance.

Hi @dmistry,

Have you tried to use a Condition action in Flow to verify the date before applying the formate date expression? 

Encapsulating this condition inside an Apply to each, could help identify if the completiondate field is getting populated or not, before attempting to formate the date.

Let me know if this helped!

Hi @dmistry 

I think you can achieve this by including a condition that checks on the date prior to updating the format, if the date exists then you can modify the format, in the other branch of the condition you can indicate date as null.

Hi @dmistry ,

Could you please share a screenshot of the configuration of your flow?

Please make sure the expression below for the CompletionDate is correct:

item()?['CompletionDate']

And then you could take a try with expression below:

if(empty(item()?['CompletionDate']),item()?['CompletionDate'],formatdatetime(item()?['CompletionDate'],'MM/dd/yyyy'))
