Fix UnsupportedParamsError

in LangChain

Solution

The "UnsupportedParamsError" in Langchain often arises when using a model or tool that doesn't support certain parameters passed to it during creation or execution, such as `tool_choice` with Bedrock. To fix this, identify the incompatible parameter by carefully reviewing the error message and the documentation for the specific model or tool you are using; then, remove or adjust the offending parameter in your Langchain code to align with the supported parameters.
