Can't evaluate `diff(diff(Fourier()))[0.0, [1]]`

[DanielVandH]

The following works:

julia> using ClassicalOrthogonalPolynomials

julia> diff(diff(Legendre()))[0.0, 1]
0.0

julia> diff(diff(Legendre()))[0.0, [1]]
1-element Vector{Float64}:
 0.0

julia> diff(diff(Fourier()))[0.0, 1]
0.0

but

julia> diff(diff(Fourier()))[0.0, [1]]
ERROR: MethodError: no method matching Int64(::Infinities.InfiniteCardinal{0})
The type `Int64` exists, but no method is defined for this combination of argument types when trying to construct it.

Closest candidates are:
  (::Type{T})(::T) where T<:Number
   @ Core boot.jl:900
  Int64(::Float64)
   @ Base float.jl:990
  Int64(::Float32)
