How to set max array length (maxArrayLength)?

Description

How to set max array length (maxArrayLength)?

Code I run

import debug from 'debug'
const log = debug('myApp');

const justArray = new Array(10_000).fill(0);
log({justArray})

const objWithNestedLongArray = {
  nestedArray: justArray
}

log({ objWithNestedLongArray})

How I have tried to set max array length

DEBUG="myApp" DEPTH_MAX_ARRAY_LENGTH="30000" bun run index.ts 

DEBUG="myApp" DEPTH_MAXARRAYLENGTH="30000" bun run index.ts

DEBUG="myApp" DEPTH_maxArrayLength="30000" bun run index.ts

Result

Despite all the 3 methods I have tried to set max array length I get the same result:

  myApp {
  myApp   objWithNestedLongArray: {
  myApp     nestedArray: [
  myApp       0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,

Additional Info

https://www.npmjs.com/package/debug#environment-variables chapter in documentation tells that by using DEBUG_ I can set Options object that gets used with %o/%O formatters like DEBUG_DEPTH, do I misunderstand that part?

[Qix-]

No you don't misunderstand, in theory that should work. Have you tried setting it to 0? Otherwise, have you tried doing simply DEBUG_DEPTH=null?

I looked at the code again and wow, we shouldn't be doing it the way we are. It's not very robust / potentially not very secure (though I struggle to think of an e.g. prototype injection attack where we could exploit it).

If you can't figure it out then let me know, I'll mark this as a bug in the meantime.
