Fix TrinoUserError

✅ Solution

TrinoUserError in Langchain often arises from incompatible data types being used in operations within the agent or when interacting with data sources. Specifically, issues like attempting to add dictionaries together when the code expects a different numeric or string type can trigger the error. The fix often involves inspecting the code where the error occurs (including custom tools or agents) and ensuring that data types are suitable for the intended operations, often coercing dictionaries to strings or lists or avoiding operations that are nonsensical for dictionary elements.
