Hi
I have a Logic App creating records in dynamics from a flat file that has been converted to JSON - however, one of the fields being passed is usually a date but is not always is not always populated with a date but populated with a '?' and this is what is causing my issue.
For files that have this value I want to ignore or send null Dynamics - if(equals(items('For_each_2')?['col16'],'?'),null,......... which evaluates correctly but fails to update Dynamics 'null' or '' doesn't work either.
Did you ever find a way to set/update a value to null in a datetime field using your logic app?
