feat(backend): be more defensive about how we load list data from db

[ntindle]

When swapping branches back and forth, I often hit stuff in my db that is incompatible with other branches. This protects against it a bit more.

Changes 🏗️

• Adds filtering around converting data out of the db

⚡ Recommended focus areas for review Variable Initialization The store_agents variable is initialized after the loop but used in the logger.debug statement. If the loop doesn't execute (empty agents list), this could cause an undefined variable error. store_agents: list[backend.server.v2.store.model.StoreAgent] = [] for agent in agents: try: # Create the StoreAgent object safely store_agent = backend.server.v2.store.model.StoreAgent( slug=agent.slug, agent_name=agent.agent_name, agent_image=agent.agent_image[0] if agent.agent_image else "", creator=agent.creator_username or "Needs Profile", creator_avatar=agent.creator_avatar or "", sub_heading=agent.sub_heading, description=agent.description, runs=agent.runs, rating=agent.rating, ) # Add to the list only if creation was successful store_agents.append(store_agent) except Exception as e: # Skip this agent if there was an error # You could log the error here if needed logger.error( f"Error parsing Store agent when getting store agents from db: {e}" ) continue logger.debug(f"Found {len(store_agents)} agents") Error Handling The error handling is very generic. Consider adding more specific exception types or capturing more details about the problematic agent to help with debugging. except Exception as e: # Skip this agent if there was an error logger.error( f"Error parsing LibraryAgent when getting library agents from db: {e}" ) continue
