The example "ball with mesh refinement" prints errors: TypeError: <lambda>() takes 5 positional arguments but 6 were given

Adding an extra argument "lc" in the lambda definition of the example removed the issue in my case.

# ball with mesh refinement
from math import sqrt
import pygmsh

with pygmsh.occ.Geometry() as geom:
    geom.add_ball([0.0, 0.0, 0.0], 1.0)

    geom.set_mesh_size_callback(
        lambda dim, tag, x, y, z, lc: abs(sqrt(x ** 2 + y ** 2 + z ** 2) - 0.5) + 0.1
    )
    mesh = geom.generate_mesh()
