原文外掛簡介

RAG Chat for Amazon Bedrock is a WordPress plugin that seamlessly integrates your WordPress content with Amazon Bedrock Knowledge Bases to create an intelligent RAG (Retrieval-Augmented Generation) chatbot system.
Key Features:

Direct Amazon Bedrock Integration: Connects directly to Amazon Bedrock Knowledge Bases without external servers
Automatic Content Synchronization: Automatically syncs WordPress posts and pages to Amazon Bedrock when content is created, updated, or deleted
Real-time Chat Interface: Provides a chat widget for visitors to interact with your content using AI
Comprehensive Admin Interface: Four dedicated admin pages for configuration and content management
AWS Security: Uses AWS Signature Version 4 authentication for secure API communication
Content Management: Track sync status and manage which content is synchronized to Amazon Bedrock

How It Works:

Configure your AWS credentials and Amazon Bedrock Knowledge Base in the plugin settings
New WordPress posts and pages are automatically synchronized to Amazon Bedrock when saved or deleted
Existing content can be synchronized using the export function in the Content Management page
Visitors can use the chat interface to ask questions about your content
Amazon Bedrock retrieves relevant content and generates intelligent responses using your WordPress data

Requirements:

AWS account with Amazon Bedrock access
Amazon Bedrock Knowledge Base configured
Valid AWS credentials (Access Key ID and Secret Access Key)

Troubleshooting
Plugin Installation & Setup Issues
Plugin activation fails

Ensure your WordPress version meets the minimum requirement (6.6+)
Check that your PHP version is 7.4 or higher
Verify there are no plugin conflicts by temporarily deactivating other plugins

The chat interface doesn’t appear on my page

Make sure you’ve inserted the shortcode [rag_chat_ab_chat] in the correct location
Check that the plugin is activated
Verify your AWS credentials are correctly configured in the plugin settings

Content Synchronization Issues
Content sync is failing

Verify your AWS credentials have the correct permissions
Check that your Knowledge Base ID and Data Source ID are correct
Ensure your Knowledge Base has a “Custom” type data source
For existing content, use the “Export Posts and Pages to Amazon Bedrock” feature on the Content Management page

Export operation times out
If you have many posts and pages, “Export Posts and Pages to Amazon Bedrock” may take a long time and cause timeout errors depending on your PHP settings. To reduce the risk of timeout:

Export content in smaller batches by selecting specific date ranges
Consider increasing your PHP execution time limit if you have server access
Contact your hosting provider if timeout issues persist
For large-scale exports, we offer a dedicated bulk export PHP script that runs independently on your server and can handle large volumes of content without web browser timeout limitations. Contact us at https://tally.so/r/3jjoga for more information about our bulk export solution

AWS Authentication & Permissions
AWS permission errors

Double-check all required IAM permissions are granted to your user
Verify your AWS Access Key ID and Secret Access Key are correct
Ensure your AWS account has access to Amazon Bedrock in the selected region
Check the AWS CloudTrail logs for detailed error information

AWS Marketplace subscription error
If you encounter “Model access is denied” with “aws-marketplace:ViewSubscriptions” permission errors:

Your IAM user needs the aws-marketplace:ViewSubscriptions permission
Add this permission to your IAM user’s policy
Wait 15 minutes after fixing the permissions before trying again
This is required for AWS Marketplace subscription completion

Model Access & Configuration
Model use case details required
If you encounter an error like “Model use case details have not been submitted for this account. Fill out the Anthropic use case details form before using the model”:

Anthropic requires use case details before using their models
Fill out the Anthropic use case details form in your AWS console
Wait 15 minutes after submitting before trying again
See the AWS documentation: https://docs.aws.amazon.com/bedrock/latest/userguide/model-access.html

Inference profile required error
If you get an error like “Invocation of model ID anthropic.claude-haiku-4-5-20251001-v1:0 with on-demand throughput isn’t supported. Retry your request with the ID or ARN of an inference profile”:

Some models require using inference profiles instead of direct model invocation
Use the ID or ARN of an inference profile that contains the model
Configure inference profiles in your Amazon Bedrock settings
See the AWS documentation: https://docs.aws.amazon.com/bedrock/latest/userguide/cross-region-inference.html

Chat responses are not working

Verify that your AWS region is correct in the plugin settings
Check that your Knowledge Base contains synchronized content
Ensure your IAM user has bedrock:RetrieveAndGenerate permissions
Try asking questions related to your synchronized content

External services
This plugin uses the following Amazon Bedrock API endpoints provided by Amazon Web Services, Inc.:

PUT https://bedrock-agent.{$region}.amazonaws.com/knowledgebases/{$knowledge_base_id}/datasources/{$data_source_id}

Called when a post or page is created or updated.
