Bedrock Agents - Knowledge Base Response Template Not Available for Editing

Hi there. Can you check if your Amazon knowledge Base is synced and that you have prepared your agent. A knowledgebase should be registered in your agent and you should have saved and exited. When you now move to orchestration you should have a knowledgebase response template that you can activate, see attached image.

If you are still having issues can you provide the following information.

• How is your knowledgebase configured. How are you sourcing data S3, document upload, custom, web crawler, etc. Are you using only unstructured data or are using Knowledgebase structured data from Redshift.
• When was your knowledgebase and agent created.
• What embedding model and vector store are you using.

The issue you're experiencing with not being able to edit the Knowledge Base Response Template in your Bedrock Agent configuration is likely due to the current limitations of the console interface for Bedrock Agents.

As of now, the console interface for Bedrock Agents does not provide direct access to edit the Knowledge Base Response Template. The console typically only allows editing of the pre-processing, orchestration, and post-processing templates, which aligns with what you're seeing.

To work around this limitation and potentially influence how your agent handles knowledge base responses, you have a few options:

1. Modify the orchestration template: You can include specific instructions in the orchestration template to guide how the agent should handle and format responses from the knowledge base. This can include directives on citation inclusion, response structure, or how to integrate knowledge base information into the final response.

2. Use a custom parser Lambda function: By implementing a custom parser, you can have more control over how the agent processes and formats responses, including those from the knowledge base. This allows you to define exactly how you want the knowledge base information to be presented in the final output.

3. Adjust the system prompt: While not directly editing the Knowledge Base Response Template, modifying the system prompt can influence how the agent interprets and uses information from the knowledge base.

4. Consider using the API or SDK: If you require more granular control over the agent's configuration, including the Knowledge Base Response Template, you might need to use the Bedrock API or SDK instead of the console. These programmatic interfaces often provide access to more advanced configuration options that may not be available through the console interface.

If editing the Knowledge Base Response Template is crucial for your use case, you may want to reach out to AWS Support for the most up-to-date information on whether this capability is available or planned for future updates to the console interface.
