Fix NoRegionError

✅ Solution

The "NoRegionError" in anthropic-sdk usually arises when the AWS region isn't explicitly configured or cannot be automatically detected from your environment. To fix this, explicitly configure the AWS region when initializing your Bedrock client, either through environment variables (AWS_REGION or AWS_DEFAULT_REGION) or by passing the `region_name` parameter directly to the Bedrock client constructor. Ensure your configured region matches where your Bedrock resources are deployed.
