Lex Integration Issue: Audio Inputs Failing with Bedrock Agent Intent While Text Inputs Work Successfully

0

I am using aws lex with the built-in intent called 'BedrockAgentIntent' so the bot uses a created bedrock agent to answer user requests, it is working from the console, but when I do it through the SDK, I get this error:

Invalid Bot Configuration: Amazon Lex could not access your Amazon Bedrock Agent. There is a problem with your config urationFailed to validate request sent to Bedrock Agent

Note that:

When I send TEXT the bot answers, whether from the agent intent, or any other intent that has predefined responses. When I send AUDIO the error occurs. I think this behavior is a bit strange.

I've attached the 'AmazonBedrockFullAccess' policy to the Lex's execution role, but still the error persists, so I think this is not a permission issue.

I would appreciate if someone provide some help, the gen AI answer is not helpful

The issue you're experiencing with audio inputs failing while text inputs work successfully for your Lex bot using the BedrockAgentIntent is indeed unusual. Based on the error message you're receiving, it appears there might be a configuration problem specifically related to how Lex is trying to access the Bedrock Agent when processing audio inputs.

Here are a few steps you can take to troubleshoot and potentially resolve this issue:

  1. Check IAM Permissions: Ensure that the IAM role associated with your Lex bot has the necessary permissions to invoke Bedrock, especially for audio processing. There might be different permission requirements for audio vs. text inputs.

  2. Verify Service Role Configuration: Double-check that Lex's service role is properly configured to interact with Bedrock, particularly for audio processing tasks.

  3. Cross-Account Settings: If Lex and Bedrock are in different AWS accounts, verify that the proper cross-account role settings are in place and that they cover both text and audio processing scenarios.

  4. SDK Configuration: When making the SDK call, ensure you're using the correct region, using credentials with proper permissions, and properly configuring the SDK client. Pay special attention to any audio-specific settings or parameters.

  5. Session ID Length: There's a possibility that the session ID length could be causing issues. Try using a session ID that is 32 characters long instead of 64 characters, as this has resolved similar issues for some users.

  6. Check Bedrock Agent Configuration: Review your Bedrock Agent configuration to ensure it's set up correctly to handle both text and audio inputs from Lex.

  7. AWS Support: If the issue persists after trying these steps, it may be worth contacting AWS Support for more detailed assistance, as this behavior suggests a potential bug or limitation in the integration between Lex and Bedrock for audio inputs.

Remember to test your changes incrementally to identify which specific adjustment resolves the issue.
