Hey, first step—dump the error logs and look for patterns, even if they’re scattered. Pinpoint the exact stack trace lines, then trace back to the original source code that’s calling that line. Once you isolate the culprit, you can test that snippet in isolation, tweak inputs, and see if the error reproduces. If the system is too opaque, write a small wrapper around the problematic function to log all inputs and outputs; that’ll give you a clean audit trail. Finally, if the legacy code is still in its original language, try compiling it in a controlled environment to surface any hidden dependencies. That’s usually the fastest way to cut through the noise.

Sounds good. Log dump first, then sift through the stack traces for repetition. Once I isolate the offender, I’ll fire up a quick unit test on that call. Your wrapper idea will help expose state leaks. Then we’ll cherry‑pick any missing libs and run the whole thing in a clean sandbox. I can have a rough timeline by end of the week, but if something stalls I’ll flag it immediately. Let’s keep it tight and avoid extra fluff.

Got it, lock in the log dump first and flag the most repeated traces. I’ll isolate the bad call, spin up a unit test, and we’ll run the wrapper you set up to surface any hidden state issues. Once we’re sure the culprit’s nailed down, I’ll pull in the missing libs in a clean environment. I’ll keep the schedule tight and ping you if something stalls. Let's keep this lean.
