Agent Builder unable to query through OAuth

[BaptisteLDS]

Hi, 

I am working on implementing an Agent Builder agent to translate user queries into multiple client APIs call. The given APIs authentication system works with OAuth.

1. Issue: Agent is not able to query via the API.
2. Error : "Failed to generate response"
3. Tried: Authentication parameters have been rechecked.
   • client-id: REDACTED
   • client-secret: REDACTED 
   • OAuth endpoint URL: REDACTED

Moreover, no traffic traces are found on the API for this client-id. It seems like the agent is not able to authenticate properly via the given config.
How can this behavior be fixed ?

Thank you, 
Baptiste

Update : It looks like there is no turnaround this issue and needs to be done by hand in some other way. https://cloud.google.com/dialogflow/cx/docs/concept/playbook/tool

Hi @BaptisteLDS,

Welcome to Google Cloud Community!

To troubleshoot the "Failed to generate response" error in your Agent Builder agent when interacting with an OAuth-protected API, let's consider the following:

Verify Authentication Configuration:

• Double-check credentials: Ensure that the client ID, client secret, and OAuth endpoint URL are correct and have the necessary permissions.
• Test authentication manually: Try to authenticate with the API using the same credentials and endpoint URL outside of the agent to verify that the authentication flow is working correctly.
• Consider OAuth flow: Determine the specific OAuth flow (e.g., Authorization Code, Client Credentials) required by the API and ensure your agent is configured to follow it correctly.

Debug Agent Behavior:

• Enable logging: Increase the logging level in your agent's configuration to get more detailed information about the requests and responses.
• Inspect network requests: Use browser developer tools or network monitoring tools to inspect the HTTP requests sent by the agent to the API. Look for errors, missing headers, or incorrect parameters.
• Simulate API calls: Create a simple script or function to simulate the API calls made by the agent. This can help isolate the issue and identify specific problems with the authentication or request parameters.

Consider API Rate Limits and Throttling:

• Check API rate limits: If the API has rate limits, ensure that your agent's requests are within the allowed limits.
• Implement retry logic: Consider implementing retry logic in your agent to handle temporary errors or rate limit issues. You can use an exponential backoff strategy, especially in scenarios where requests to a server or API might fail due to rate limiting. 

Just to add, Playbook in agent builder is currently in Preview, which means it is still under development and may not yet offer the expected quality. Preview features often come with certain limitations and might not provide the full range of quality or functionality available in the final product. It may have bugs or unexpected behaviors. You can expect the quality to improve as the feature matures. 

I hope the above information is helpful.
