How to deploy:

Configure your account id:

• goto bin/knowledgebase.ts
• change YOUR_ACCOUNT_ID in defaultStackProperties.

Install Dependencies

npm i

Deploy the solution:

npx cdk deploy --all

How to test:

Once everything is deployed:

• go to your AWS Account
• go to the lambda function resolveQuestion
• invoke it with test event {"question":"How to reset password?"}

Extras:

You can also add your own documents to documents and just redeploy knowledgebase-example-agent-knowledgebase.
This will trigger a startIngestionJob, which will re-index your knowledge base with the new documents.
