jq -r '.issue.number' can yield the literal string null if the expected field is missing, which won’t trip the -z "$target_number" guard and can later break gh api .../issues/$TARGET_NUMBER / --argjson targetNumber "$TARGET_NUMBER". Consider treating null as empty (e.g., via // empty) so the workflow reliably skips instead of failing on unexpected payload shapes.
