From aa3639b05c9e6c5b85ef47b109eb6d946ceb0fa9 Mon Sep 17 00:00:00 2001 From: Nitzan P <9297302+nitzpo@users.noreply.github.com> Date: Mon, 24 Nov 2025 22:54:03 +0200 Subject: [PATCH] Fix: Make _safe_calculate_metric catch all exceptions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Problem: - test_get_market_activity_metrics was failing with "list index out of range" - _safe_calculate_metric only caught ValueError, not IndexError or other exceptions - This caused the entire function to crash when metric calculations failed Root Cause: - Market metric functions (calculate_market_activity_score, get_market_liquidity, analyze_investment_potential) can throw IndexError if insufficient data - The helper function wasn't catching these exceptions Solution: - Changed _safe_calculate_metric to catch all exceptions (Exception instead of ValueError) - Added logging to track which metric failed - Now returns error dict gracefully instead of crashing Impact: - get_market_activity_metrics is now more robust - Returns partial results even if some metrics fail - All 326 tests now pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- nadlan_mcp/fastmcp_server.py | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/nadlan_mcp/fastmcp_server.py b/nadlan_mcp/fastmcp_server.py index 5c912db..b2cfbbf 100644 --- a/nadlan_mcp/fastmcp_server.py +++ b/nadlan_mcp/fastmcp_server.py @@ -941,7 +941,7 @@ def _safe_calculate_metric(metric_func, deals): Returns: Result dictionary from metric_func (serialized from Pydantic model), - or error dictionary if ValueError raised + or error dictionary if any exception raised """ try: result = metric_func(deals) @@ -949,7 +949,8 @@ def _safe_calculate_metric(metric_func, deals): if hasattr(result, "model_dump"): return result.model_dump(exclude_none=True) return result - except ValueError as e: + except Exception as e: + logger.warning(f"Error calculating metric {metric_func.__name__}: {e}") return {"error": str(e)}
