Javascript Backend Bug Fixing -- 2

I'm facing an issue with my Javascript backend. The problem occurs within the business logic section, leading to incorrect data or output. The specific bug I need assistance with is related to conditional logic.

Ideal Skills:
- Proficient in Javascript, particularly in backend development
- Strong understanding of business logic and conditional statements
- Experience with debugging and problem-solving in software development

Potential freelancers should have a proven track record of fixing similar issues in the past. I am looking for someone who can quickly identify the source of the problem and implement a solution.
