sourcemap: runtime error: index out of range [-1] #3556
Description
Brief summary
I build with TS some load tests, they are compiled with Vite (Babel and Rollup) in JavaScript. The sourcemap support works fine, except for this file: k6-jslib-aws-y_ANwLL3.cjs.zip (the sourcemap is embedded as the last line of the file)
k6 version
v0.46.0
OS
Docker container with Alpine linux (Host: macOS 14.2.1)
Docker version and image (if applicable)
Custom image with this base images: golang:1.20-alpine + alpine:3.17
Steps to reproduce the problem
- Install
k6-jslib-awsfrom Github with npm, to have full TS support:
npm install --save github:grafana/k6-jslib-aws#v0.11.0- Import the attachted
k6-jslib-aws-y_ANwLL3.cjsfile and cause an error with empty AWS credentials
import { AWSConfig } from "k6-jslib-aws-y_ANwLL3.cjs";
new AWSConfig({
region: "",
accessKeyId: "",
secretAccessKey: "",
sessionToken: "",
});Expected behaviour
Show an error with correct sourcemap lookup like this
ERRO[0000] Error: invalid AWS access key ID; reason: size should be between 16 and 128 characters, got 5

Actual behaviour
A thrown JS error cause this Go runtime error:

Interestingly, the runtime error only occurs when I repeat the execution in quick sequence only in the first execution. The other executions show the correct JS error.
By the way: Why this go build does not install the latest version (0.46 instead 0.48)?
go install go.k6.io/xk6/cmd/xk6@latest
xk6 build \
--with github.com/grafana/xk6-dashboard \
--output /tmp/k6
