Solution

This error happens when the controller action method requires the parameter of type unique identifier and no parameter or null or different type of parameter is passed to the action method
I got this error while I was trying to redirect to the edit method from the create method
the problem was with the code below

   

return RedirectToAction("Edit", "Recipe", recipe.Id);

  

return RedirectToAction("Edit", "Recipe", new { id = recipe.Id } );
