SSometimes when you build and run a Javascript file in Node, some TypeErrors can pass through ESBuild checks and they're difficult to understand directly... l

To visualize a screen portion of code you can try writing this:

#!/bin/bash
max=$(( $1+10 ))
length=20
cat -n $2 | head --lines=${max} | tail --lines=${length}

save it to "see-lines.sh" and setup it in your project structure and invoke it with the error stack trace line number:

./see-lines 421 dist/index-bundled.js

Et voilà !
