`ERROR: LoadError: Invalid text boundingbox` with colorbars/heatarrays

[Datseris]

MWE:

using Agents
using InteractiveDynamics
import GLMakie

@agent Person GridAgent{2} begin
    wealth::Int
end

function agent_step!(agent, abm)
    agent.wealth == 0 && return # do nothing
    na = collect(nearby_ids(agent, abm))
    if !isempty(na)
        n = rand(abm.rng, na)
        abm[n].wealth += 1
        agent.wealth -= 1
    end
end

# with filled space
function wealth_abm_filled(; dims = (25, 25), init = 4)
    space = GridSpace(dims, periodic = true)
    abm = ABM(Person, space; scheduler = Schedulers.randomly)
    fill_space!(abm, init)
    return abm
end

abm = wealth_abm_filled()

function wealthmap(abm)
    m = zeros(Int, size(abm.space))
    for pos in positions(abm)
        for a in agents_in_position(pos, abm)
            m[pos[1], pos[2]] += a.wealth
        end
    end
    return m
end

cmap = GLMakie.cgrad(:tokyo, 100)

ac(a) = cmap[a.wealth/10]

abm_play(abm, agent_step!, dummystep; ac, heatarray = wealthmap)

and I get:
