I have a recurrence flow that runs once a day and needs to check whether a custom datetime SharePoint (modern) column, NextReview, is empty or not. After the get items action there is a condition control with:
@empty(triggerBody()?['NextReview'])
but it always returns true, that is it takes the next action on the basis that it thinks the column in SharePoint is empty which is not the case. I've not had this problem with SharePoint lists, it only seems to affect document libraries and seems to happen whatever the column type. It looks to be a bug but does anyone have a suggestion for a way round it?
