It recommends catching specific exception types (`ImportError`, `AttributeError`, `RuntimeError`) instead of a broad `Exception` to avoid masking unexpected errors. This improves error handling by making it more explicit and targeted, which aligns with best practices in Python development. **superset/mcp_service/chart/validation/runtime/__init__.py** ``` except (ImportError, AttributeError, RuntimeError) as exc: ``` ########## superset/mcp_service/chart/plugins/xy.py: ########## @@ -0,0 +1,196 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.
