How to use NonEmpty within a template

G-d willing

Hello,
I want to use the NonEmpty for a list of Decimals within a template, and I can’t find a way in doing so.
When I am doing it on a regular data type it works okay, as follows:

let nums = NE.NonEmpty
          with
            hd = 2
            tl = []

But when I am trying to do the same on a template I am getting an error.

template NonEmptyTest
  with 
    sideA: Party
    nums: NE.NonEmpty [Int]
  where
    signatory sideA

setup : Script ()
setup = script do

  alice<- allocatePartyWithHint "Alice" (PartyIdHint "Alice")

  submit alice do
    createCmd NonEmptyTest 
      with 
        sideA=alice
        nums= NE.NonEmpty 
          with 
            hd = 2
            tl = []

Can you please tell me what am I doing wrong?

Your template defines nums to be a non-empty list of lists of integers. However, you are trying to use it as a non-empty list of integers so without the extra level of lists.

Change the type to nums : NE.NonEmpty Int and it should work.
