refactor: use optional chaining for concise error message parsing

Refactors lineColMatch array access to use optional chaining (?.[])
instead of logical AND (&&) operators, making the code more concise
and easier to read. This addresses SonarQube code quality suggestions
while maintaining identical functionality.

Changes:
- Line 233: lineColMatch ? lineColMatch[1] → lineColMatch?.[1]
- Line 234: lineColMatch && lineColMatch[2] → lineColMatch?.[2]
