Python & Java Error Debugging

Job ID: 39928710

Budget: ₹750 – ₹1,250 INR

I need the errors that are crashing both my Python scripts and Java classes traced, fixed, and verified. The issues show up during runtime, so I will provide the source files together with the current stack traces and any relevant logs.

Your job is to:
• locate the exact fault in each language
• apply clean, well-commented fixes without altering unrelated logic
• run the programs with representative data to confirm stability
• send back the corrected files plus a concise changelog that explains what you did and why

I have firm time limits on this task, so please be ready to start right away and keep me updated with quick checkpoints until everything runs smoothly.
