List.Dates function- Count error

Hi

As an example, I have a table in the below format.

I want to create a table that has every date allocated to a period. I have created a custom column as per the below:

Table.AddColumn(#"Removed Columns", "Custom", each List.Dates([startingDate], Number.From([endingDate]-[startingDate])+1, #duration(1,0,0,0)))

This gives the desired output but when trying to apply these changes it comes back with the following error.

OLE DB or ODBC error: [Expression.Error] The 'count' argument is out of range..

I can't work out why this is, does anyone else know?

Thanks in advance,

Ross
