Does not work in julia 1.11.5

[Liozou]

This is a very nice package, thank you for developing it! Unfortunately it seems not to work if the client uses Julia 1.11.5. For example, after opening a server (using Julia 1.11.5) serving on port 12121, there is no issue if the client is on Julia v1.11.4:

julia> VERSION
v"1.11.4"

julia> using RemoteREPL

julia> connect_repl(12121)
[ Info: Using session id 20ade862-1cc6-40d7-83ca-c09254de176b
REPL mode remote_repl initialized. Press > to enter and backspace to exit.
"Prompt(\"julia@localhost:12121> \",...)"

julia@localhost:12121> 1+5
6

However, if the client is on Julia v1.11.5 it crashes with an illegible stacktrace, because the REPL throws an error while trying to show the error...

Did you have to do anything special to get it working with Julia 1.11.4?

It works fine with 1.10, but all versions of 1.11 fail for me with

julia> connect_repl()

No special trick no, I'm using v1.11.4 on both server and client ends, is that the case for you too?

I simply run julia +1.11.4 --startup-file=no --project=@temp on both server and client ends. The server code is:

julia> using RemoteREPL

julia> x = 17
17

julia> serve_repl(12121)

and the client session is:

julia> using RemoteREPL

julia> connect_repl(12121)
[ Info: Using session id 27b8ca79-d1dc-4b76-9ec9-b8c74b23cf98

"Prompt(\"julia@localhost:12121> \",...)"

julia@localhost:12121> x
17
