When an date & time node receives null. It will still transform it to a date. In my opinioin this does not make sense. It should just leave it null. I have tried other methods to skip the node with a IF node but then other problems arrives in the rest of the flow as the node is not executed but there is a link to it.
Hi @timautomation, I am sorry you’re having trouble. I shall add this to our bug tracker for a closer look and fix. This might not get the highest priority though since a more capable alternative to the Date & Time node is available.
So perhaps you want to consider using the Set node until this is fixed, like shown below?
