a panic occurred during JS execution

[valerypetrov]

Hey Grafana Team,

During the evaluation and running xk6-client tracing, I found that if you put a value higher than 5000 vus, the xk-6-client tracing tool may return the following error:
ERRO[0006] a panic occurred during JS execution: runtime error: index out of range [-1]

I've put the following value for the options setting:

export const options = {
    vus: 10000,
    duration: "20m",
};

xk-6-client version:

ENDPOINT=http://endpoint:3317 ./k6-tracing version
k6-tracing v0.48.0 (go1.22.0, linux/amd64)
Extensions:
  github.com/grafana/xk6-client-tracing (devel), k6/x/tracing [js]

If it matters, I've run it on the VM:

cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="9.2"
