Geant4 throwing error after new update

[rajxabc]

after updating SolidStateDetectors package, i am getting following when trying to run test_geant4,jl or any "G4JLApplication(sim, source_1)" ...
Run Geant4 simulations: Error During Test at h:\Raj_Julia\test_geant4.jl:57 Got exception outside of a @test MethodError: no method matching length(::Tuple{}) You may have intended to import Base.length The functionlength` exists, but no method is defined for this combination of argument types.

Closest candidates are:
length(::Union{Ptr{Nothing}, CxxWrap.CxxWrapCore.ConstCxxPtr{<:Geant4.G4ProcessVector}, CxxWrap.CxxWrapCore.CxxPtr{<:Geant4.G4ProcessVector}})
@ Geant4 C:\Users\rajsi.julia\packages\CxxWrap\I0P2E\src\CxxWrap.jl:676

@ Geant4 C:\Users\rajsi.julia\packages\CxxWrap\I0P2E\src\CxxWrap.jl:676

kindly suggest some solution/rectification

Explicitly request Geant4@0.2.2 or newer:
#503

Thank You
For me these steps worked

in VScode Terminal

]
(@v1.11) pkg> rm MeshViz
(@v1.11) pkg> rm Makie
(@v1.11) pkg> rm IntervalSets
(@v1.11) pkg> rm Geant4

import Pkg; Pkg.Registry.update(); Pkg.activate(); Pkg.instantiate();

Restart VScode

import Pkg;
Pkg.add(Pkg.PackageSpec(name="Geant4", version="0.2.2"))

Restart VScode

I think if you explicitly request
]add Geant4@0.2.2,
that should also do it (maybe also ]pin Geant4) to prevent it from downgrading again

got it thanks
