Hello!
I'm running into this issue in my Flow- Error details: Input parameter 'item/First_x0020_Steps_x0020_Due_x002' is required to be of type 'String/date'. The runtime value '"44137"' to be converted doesn't have the expected format 'String/date'.
Here is what I'm trying to do- create a flow that takes rows on the Excel spreadsheet and enter them (if they don't already exist) to a Sharepoint List. Here's what the spreadsheet looks like- I would manually enter Columns A-E and all the due dates are calculated based on a formula that subtracts days from Column C.
My flow works with Columns A-E, but it fails on the calculated date columns- here's what that section looks like with the Error message- 
(In a separate flow, I'm using this Sharepoint List to create Tasks in Planner with Due Dates- so the dates are critical.)
