Argument error for BifurcationProblem

[RpfR2000]

This is a problem I've been encountering with more or less every BifurcationKit example online. Here's an example. I try to run the following code:

using Revise, Plots
using BifurcationKit
using Accessors
const BK = BifurcationKit

function Pop!(du, X, p, t = 0)
	(;r,K,a,ϵ,b0,e,d) = p
	x, y, u, v = X
	p = a * x / (b0 * (1 + ϵ * u) + x)
	du[1] = r * (1 - x/K) * x - p * y
	du[2] = e * p * y - d * y
	s = u^2 + v^2
	du[3] = u-2pi * v - s * u
	du[4] = 2pi * u + v - s * v
	du
end

par_pop = ( K = 1., r = 6.28, a = 12.56, b0 = 0.25, e = 1., d = 6.28, ϵ = 0.2, )

z0 = [0.1,0.1,1,0]

prob = BifurcationProblem(Pop!, z0, par_pop, (@optic _.b0);
	record_from_solution = (x, p; k...) -> (x = x[1], y = x[2], u = x[3]))

opts_br = ContinuationPar(p_min = 0., p_max = 20.0, ds = 0.002, dsmax = 0.01, n_inversion = 6, nev = 4)

and I get the following error:

ERROR: LoadError: MethodError: no method matching BifurcationProblem(::BifFunction{…}, ::Vector{…}, ::@NamedTuple{…}, ::PropertyLens{…}, ::typeof(BifurcationKit.plot_default), ::var"#10#12")

Closest candidates are:

Stacktrace:

By the way, I think Accessors.jl is a necessary dependency to get the optic macro now (maybe this was not the case previously).

What is your version of BK?

[RpfR2000]

v0.3.3

You hsve to usr 0.4

I see, thanks!
