IPython mode seems to cause error: `type MD has no field args`

[singularitti]

I am using ReplGPT on my system and come across the following error:

using ReplGPT

ReplGPT.setAPIkey("my-key")

It seems to be caused by Julia v1.9's IPython mode in my startup.jl. When I comment these lines, the error disappears:

using REPL
atreplinit() do repl
    if !isdefined(repl, :interface)
        repl.interface = REPL.setup_interface(repl)
    end
    REPL.ipython_mode!(repl)
end
