Unable to add multiple addressPrefixes to VNET?

Does this work? I think you are currently technically passing the vnet.properties.addressSpaces property an array of arrays, not a single array.

resource vNet1 'Microsoft.Network/virtualNetworks@2020-06-01' = [for vnt in vNet: {
  ...
  properties: {
    addressSpace: {
      addressPrefixes: vnt.addressspace // address space is an array, so can be provided directly, not inside another array
    }
    ...
  }
}
