Why did the confederation congress call for a constitutional convention?

The Confederation Congress called for a Constitutional Convention because Confederation congress worked brilliantly during the time of war, but they could not work during th peace time. It was time for the formation of a centralized government that would look after the needs of the coutry and its citizens.There was a definite lack of money from the central government as none existed.
