Fix: Monitoring Workflow Test Failure - Agent Invocation Error

by ADMIN 63 views

Hey guys! We've got a situation on our hands – a test failure in our monitoring workflow integration. Let's dive into the details, figure out what went wrong, and get this fixed ASAP. This article breaks down the test failure, the root cause, impact, steps to reproduce, and provides a detailed investigation guide to help you resolve the issue.

Test Failure Details

This failure was detected by Claude Code's nightly test analysis, so a big shoutout to Claude for catching this! The specific workflow run that triggered the alert can be found here. Let's look at the specifics of what went wrong.

Failing Test

  • File: tests/integration/monitoring-workflow.integration.test.ts:91
  • Test: "should track complete orchestration workflow and support all monitoring commands"

This test is crucial because it ensures our monitoring system correctly tracks the entire orchestration workflow and that all monitoring commands are functioning as expected. A failure here indicates a potential issue with our core monitoring capabilities, so let's get to the bottom of it.

Error Message

The error message we received is pretty clear:

AssertionError: expected true not to be true // Object.is equality
    at /home/runner/work/levys-awesome-mcp/levys-awesome-mcp/tests/integration/monitoring-workflow.integration.test.ts:91:38

This AssertionError tells us that something unexpected happened during the test. Specifically, the test expected a value to not be true, but it was true. In simpler terms, an error was detected when it shouldn't have been. Let's dig deeper into the root cause.

Root Cause

The heart of the issue lies in the assertion within the test. The test is failing because the agent invocation result contains an error. Let's break down the code snippet that's causing the trouble:

const invokeResult = await handleAgentInvokerTool('invoke_agent', {
  agentName: 'backend-agent',
  prompt: `Create a file backend/monitoring-test.txt with content "Monitoring integration test - ${new Date().toISOString()}"`,
  taskNumber: 1,
  sessionId: testSessionId,
  invokerAgent: 'orchestrator-agent'
});

expect(invokeResult.isError).not.toBe(true); // Line 91 - FAILING

In this snippet, we're invoking the backend-agent to create a file. The test then checks if the invokeResult.isError property is true. The test is designed to ensure that the agent successfully completes its task without errors. However, the backend-agent invocation is unexpectedly returning isError: true, meaning the agent failed to complete the file creation. This is a big clue for us!

Impact

So, why is this failure a big deal? Well, this particular test failure directly impacts the monitoring workflow integration. This integration is vital for several reasons:

  • Orchestrator Tracking: It validates that our Orchestrator agent can effectively track agent invocations.
  • Task Progress Monitoring: It ensures we can monitor the progress of tasks within our system.
  • Lifecycle Event Recording: It guarantees that orchestration lifecycle events are correctly recorded.

If this integration is broken, we might miss critical events, have inaccurate task progress information, or lose track of agent activities. This can lead to significant issues in our overall system monitoring and management. Basically, we'd be flying blind, and nobody wants that!

Steps to Reproduce

Want to see the failure in action? No problem! Here’s how you can reproduce it:

  1. Run this command in your terminal: npm test tests/integration/monitoring-workflow.integration.test.ts
  2. Observe that the backend-agent invocation returns an error.
  3. See the test fail at the assertion checking for the error status.

By following these steps, you can confirm the issue and start your investigation. Now, let’s move on to some suggested investigation steps to help you nail down the exact cause.

Suggested Investigation

Alright, time to put on our detective hats and figure out what's causing this agent invocation error. Here's a step-by-step guide to help you investigate:

1. Check Backend-Agent Configuration and Invocation

First things first, we need to ensure that the backend-agent is correctly configured and can be invoked. Here’s what you should look at:

  • Agent Status: Is the backend-agent running and accessible? You might want to check its logs or status endpoints to confirm it's operational.
  • Configuration Settings: Are all the necessary configuration settings for the backend-agent correctly set? Double-check things like API keys, database connections, and any other relevant parameters.
  • Invocation Parameters: Review the parameters being passed to the handleAgentInvokerTool function. Are we passing the correct agentName, prompt, and other necessary data? Pay close attention to the prompt – is it correctly formatted and making the right request?

It's possible that a simple misconfiguration or an inaccessible agent is the root cause. Let's rule this out first.

2. Verify File Creation Permissions

Next up, let's make sure the backend-agent has the necessary permissions to create files in the backend directory. This is a classic issue, so it's worth checking:

  • File System Permissions: Does the user or service running the backend-agent have write permissions to the backend directory? You might need to adjust file system permissions to allow the agent to create files.
  • Directory Existence: Does the backend directory actually exist? It might sound silly, but it's easy to overlook. Ensure the directory is present and accessible.
  • Storage Quotas: Are there any storage quotas or limitations that might be preventing the agent from creating files? Check for any such restrictions on the file system or storage service being used.

If the agent doesn't have the right permissions, it will definitely fail to create the file, leading to the isError: true response.

3. Review Recent Changes

If the agent and permissions seem fine, the next step is to review recent changes to the agent-invoker tool or the backend-agent itself. This is where your Git history becomes your best friend!

  • Code Commits: Look through recent commits to both the agent-invoker tool and the backend-agent repository. Did anyone make changes that might have introduced a bug? Pay attention to changes related to file handling, error reporting, or agent invocation logic.
  • Dependency Updates: Were there any recent dependency updates? Sometimes, updates to libraries or frameworks can introduce unexpected behavior. Try reverting to previous versions of dependencies to see if that resolves the issue.
  • Configuration Changes: Were there any recent changes to configuration files or environment variables? A simple typo in a configuration setting can cause all sorts of problems.

By reviewing recent changes, you might spot a potential culprit that slipped in unnoticed.

4. Check Logs for the Actual Error Message

Finally, and perhaps most importantly, let's dive into the logs! The logs should contain the actual error message returned by the agent, which can provide invaluable clues.

  • Agent Logs: Check the logs for the backend-agent. Look for any error messages, stack traces, or warnings that might indicate what went wrong during the file creation attempt.
  • Agent-Invoker Logs: Also, check the logs for the agent-invoker tool. It might provide additional context or error information related to the invocation process.
  • System Logs: Don't forget to check system logs! Sometimes, errors are logged at the system level and might not appear in the agent-specific logs.

The actual error message can give you a clear direction for your investigation. For example, it might reveal a specific exception, a missing dependency, or a failed API call.

Let's Get This Fixed!

By following these investigation steps, you should be well on your way to identifying the root cause of the test failure. Remember, the key is to be methodical and thorough in your investigation. Start with the basics, like configuration and permissions, and then move on to more advanced steps, like reviewing code changes and logs.

Once you've identified the cause, fixing it should be straightforward. Whether it's a simple configuration tweak, a code fix, or a permission adjustment, you'll be able to get the monitoring workflow integration back on track.

So, let’s get to it, guys! Let's squash this bug and ensure our monitoring system is rock solid. Good luck, and happy debugging! Remember, a well-tested system is a happy system, and a happy system makes for a much less stressful day.
