Can't evaluate Legendre series

[Veenty]

Cannot evaluate a simple Legendre series, akin to a Chebyshev series

P = Legendre()
f = P*[1.0; 2; 3; zeros(∞)]
f[0.1]  #error

[Veenty]

I suspect is because the plan_inv is not implemented?

n = 10
p_1 = chebyshevpoints(Float64, n, Val(1))
FP = plan_transform(P, p_1, 1)
FP\(FP*p_1) #error

Actually, it seems that there was a breaking change recently on the Legendre class, because

using ClassicalOrthogonalPolynomials
P = Legendre()
P[0.1, 3]

Gives the error

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.

I was stupid and did not realize that my package manager decided to install not the earliest release

Always include the full error in an issue, just typing #error makes it impossible to diagnose the issue
