Hi there,

This error is preventing my flow from running at all.  The date fields in my list are not required and will only be used on occasion.  There are 7 date field options within this list that is being filled out or left blank on the form.  I have googled a few ways to try to fix this and I am coming up short.  Any advice on how to get these to run without information being populated would be super helpful.

    I'm having the same issue here, any one could help would be appreciated a lot .. 

    i think it require to format date/Time first then use the output in the Flow Connectors.. But i don't know how to do this as well.
