Is there a way to suppress the stacktrace that accompanies an error in the Julia REPL?

Is there a way to suppress the stacktrace that accompanies an error in the Julia REPL (VS Code specific methods acceptable)? It fills my screen with a lot of output that is not useful for me to fix the error, and I regularly must scroll up through it to find the useful, single, first line of error description, and find this inefficient and messy.

VS Code specific solution

Installing the "Julia Insiders" extension instead of the regular "Julia" extension solves this issue, as explained here.

I can see the fix is merged into the main branch but for some reason it hasn't made its way into the regular extension.

Maybe not quite what you wanted, but it's close:

julia> # Sequence of dummy functions to generate long stack trace
       f() = g()
       g() = h()
       h() = k()
       k() = error("Hello world")
k (generic function with 2 methods)

julia> # Default: long stacktrace
       f()
ERROR: Hello world
Stacktrace:
 [1] error(::String) at ./error.jl:33
 [2] k() at ./REPL[72]:5
 [3] h() at ./REPL[72]:4
 [4] g() at ./REPL[72]:3
 [5] f() at ./REPL[72]:2
 [6] top-level scope at REPL[73]:2

julia> # try/catch to eliminate stacktrace
       try
           f()
       catch e
           printstyled(stderr,"ERROR: ", bold=true, color=:red)
           printstyled(stderr,sprint(showerror,e), color=:light_red)
           println(stderr)
       end
ERROR: Hello world
