Fix ParamValidationError

✅ Solution

The "ParamValidationError" in LlamaIndex usually arises from incorrect or missing arguments passed to a function or class constructor, especially when integrating with other services like Bedrock. Inspect the error message for the problematic parameter and its expected type; then, ensure that you are providing the argument with the correct type and that all required parameters are supplied during initialization, paying close attention to any changes in API requirements from external libraries.
