First, grab the stack trace and see where it actually blows up. Then check that the module is actually exporting what you think it is—if someone used `module.exports = undefined` by accident, you’re dead in the water. Sprinkle `console.log` before every import and at the start of every function; the moment the value flips to undefined is your breadcrumb. If it’s still a maze, temporarily replace the suspect part with a hard‑coded value and see if the error persists. If it doesn’t, you’ve isolated the culprit. Finally, give the dead end a name, document it, and commit the fix—then throw a half‑hearted joke at whoever wrote that last line.

Right, one print, one stack, one check for a rogue reassign of `module.exports`. That’s the classic snake in the grass. Document the change like you’re writing a murder mystery: what was wrong, why it broke, how the fix solves it. Leave the jokes for the post‑merge coffee.

Sounds like a plan—minimal logs, fix the export, tidy diff, no jokes before the PR. You’ll have it sorted in no time. Good luck!

Sounds like a solid strategy. Knock it out and you’ll have that module running smooth before anyone even notices the code was a mess. Good luck!
