Introduction

Hey guys! Experiencing a frustrating issue with Twinny where autocomplete throws a 404 error, but the chat function works perfectly fine? You're not alone! This article dives deep into this peculiar problem, exploring the potential causes and offering troubleshooting steps to get your autocomplete back on track. We'll break down the error logs, analyze the configuration, and provide practical solutions. So, if you're scratching your head over this Twinny glitch, stick around – we're here to help!

Understanding the Bug: Autocomplete 404 Error

Let's start by understanding the core issue. The user reports that autocomplete functionality in VSCode is failing, resulting in a 404 error in the logs. This means that when the user types in VSCode, Twinny attempts to fetch suggestions from the server but receives a "Not Found" error. However, the chat feature, which uses the same model, works flawlessly. This discrepancy points to a problem specifically within the autocomplete module or its communication pathway.

Error Logs Analysis

Examining the provided logs is crucial for pinpointing the problem. Here's a breakdown of the key elements:

  • Streaming Response: The logs indicate that Twinny is attempting to stream a response from 0.0.0.0:11434. This is likely the address of the Ollama server, which Twinny uses for code completion and chat.
  • Request Body: The request body contains important information, including:
    • model: The model being used is codellama:7b-code.
    • prompt: This is the code context sent to the model for generating suggestions. It includes the code snippet from the C# file (Landmark.cs) where the user is typing.
    • stream: Set to true, indicating that the response is expected to be streamed.
    • options: Specifies the generation parameters like temperature (0.2) and num_predict (512).
  • Request Options: These define the connection details:
    • hostname: 0.0.0.0
    • port: 11434
    • path: /api/generate – This is the API endpoint for generating text.
    • method: POST
    • headers: Includes Content-Type and Authorization (which is empty in this case).
  • Error Message: The critical error message is Server responded with status code: 404. This confirms that the server (Ollama) is not found at the specified path for autocomplete requests.

Identifying the Discrepancy

The key question is: why does the chat work if the autocomplete is getting a 404? Here are a few possible explanations:

  1. Different Endpoints: The chat and autocomplete features might be using different API endpoints on the Ollama server. While chat might be correctly configured, the autocomplete endpoint could be missing or misconfigured.
  2. Routing Issues: There might be a routing problem within Twinny or the underlying network configuration. Autocomplete requests might be incorrectly routed to a non-existent path.
  3. Firewall or Network Restrictions: A firewall or network policy might be blocking requests to the specific endpoint used by autocomplete.
  4. Ollama Configuration: There could be an issue with the Ollama server configuration itself, where the autocomplete endpoint is not properly exposed.

Troubleshooting Steps: Fixing the Autocomplete 404 Error

Now that we have a good understanding of the problem, let's dive into the troubleshooting steps. These steps are designed to systematically identify and resolve the 404 error.

1. Verify Ollama Server Status

First and foremost, ensure that your Ollama server is running and accessible. Here’s how you can check:

  • Check the Ollama process: Make sure the Ollama server process is running on your system. You can use your operating system's task manager or process monitoring tools to verify this.

  • Ping the server: Try pinging the server address (0.0.0.0) to ensure basic network connectivity. However, note that 0.0.0.0 represents all IPv4 addresses on the local machine, so a successful ping doesn't guarantee the Ollama service is running.

  • Access the Ollama API directly: You can use tools like curl or Postman to send a direct request to the Ollama API endpoint (http://0.0.0.0:11434/api/generate) to see if it responds. This will help isolate whether the issue is within Twinny or with the Ollama server itself. For example, you can use the following curl command:

    curl -X POST http://0.0.0.0:11434/api/generate -H "Content-Type: application/json" -d '{"model": "codellama:7b-code", "prompt": "Test prompt"}'

    If you receive a 404 error here as well, the problem is likely with the Ollama server configuration or routing.

2. Check Twinny Configuration

Next, verify that Twinny is correctly configured to connect to the Ollama server. This involves checking the settings within VSCode and the Twinny extension.

  • Extension Settings: Open VSCode settings and search for “Twinny.” Check the following settings:
    • API Endpoint: Ensure that the API endpoint is correctly set to http://0.0.0.0:11434 (or the correct address if your Ollama server is running elsewhere).
    • Model Name: Verify that the model name (codellama:7b-code or your preferred model) is correctly specified.
    • Any other relevant settings: Look for any other settings related to server connection, authentication, or API paths.
  • Configuration Files: Twinny might use configuration files to store settings. Check the Twinny documentation to locate these files and ensure they are correctly configured.

3. Investigate API Endpoints

The 404 error suggests that the autocomplete feature might be using an incorrect API endpoint. Let's investigate this further.

  • Twinny Documentation: Consult the Twinny documentation to identify the specific API endpoint used for autocomplete. It might be different from the chat endpoint.
  • Network Inspection: Use browser developer tools or network monitoring tools (like Wireshark) to inspect the actual API requests being made by Twinny when you trigger autocomplete. This will reveal the exact URL being requested and help you identify any discrepancies.
  • Ollama API Documentation: Check the Ollama API documentation to confirm the available endpoints and their expected usage. Ensure that the endpoint Twinny is using exists and is intended for autocomplete.

4. Examine Routing and Network Issues

If the API endpoint seems correct, the problem might be related to routing or network restrictions.

  • Localhost Resolution: Ensure that 0.0.0.0 or localhost correctly resolves to your local machine. Sometimes, issues with the hosts file or DNS configuration can cause problems.
  • Firewall Rules: Check your firewall settings to ensure that there are no rules blocking communication between VSCode and the Ollama server on port 11434. Add exceptions if necessary.
  • Proxy Settings: If you are using a proxy server, ensure that VSCode and Twinny are configured to use it correctly. Incorrect proxy settings can prevent requests from reaching the Ollama server.

5. Review Ollama Server Configuration

If the problem persists, the issue might lie within the Ollama server configuration itself.

  • Endpoint Mapping: Check the Ollama server configuration files to see how API endpoints are mapped. Ensure that the endpoint used for autocomplete is correctly defined and exposed.
  • Access Control: Verify that there are no access control restrictions preventing Twinny from accessing the autocomplete endpoint. This might involve checking API keys, authentication settings, or IP address whitelisting.
  • Server Logs: Examine the Ollama server logs for any error messages or warnings related to API requests. These logs can provide valuable clues about the root cause of the 404 error.

6. Reinstall or Update Twinny and Ollama

As a last resort, try reinstalling or updating Twinny and Ollama. This can resolve issues caused by corrupted installations or outdated versions.

  • Update Twinny: Check for updates in the VSCode extensions panel and install the latest version.
  • Reinstall Twinny: If updating doesn't help, try uninstalling and reinstalling Twinny.
  • Update Ollama: Follow the instructions in the Ollama documentation to update to the latest version.
  • Reinstall Ollama: If updating doesn't work, try uninstalling and reinstalling Ollama.

7. Check for Conflicting Extensions

Sometimes, other VSCode extensions can interfere with Twinny's functionality. Try disabling other extensions one by one to see if any of them are causing the 404 error.

8. Provide Detailed Information When Seeking Help

If you've tried these steps and are still facing the issue, it's time to seek help from the Twinny community or developers. When reporting the problem, provide as much detail as possible, including:

  • Twinny Version: The version of the Twinny extension you are using.
  • Ollama Version: The version of the Ollama server.
  • VSCode Version: The version of VSCode.
  • Operating System: Your operating system (e.g., Windows 10, macOS).
  • Detailed Error Logs: Include the complete error logs, not just the 404 message.
  • Configuration Details: Share any relevant configuration settings you have changed.
  • Steps to Reproduce: Clearly describe the steps to reproduce the error.
