Debugging: JSON parser issue (find/fix bug)

Debugging: JSON Parser (JsonParser) You are given a codebase/snippet that uses a JsonParser along with failing behavior (e.g., parsing errors or incorrect parsed output). Your task is to identify and fix the bug by reproducing and debugging the issue. The interviewer provides minimal guidance. Note: Without the code, error logs, and repro inputs, this can only be kept as a high-level summary.
