I.streamCompletion(...) is not a function or its return value is not async iterable: Troubleshooting Guide

When working with Large Language Models (LLMs) like Ollama, integrating them into your application can be a complex task. One common issue that developers face is the error message "I.streamCompletion(...) is not a function or its return value is not async iterable." This error can be frustrating, especially when other LLM clients work seamlessly with your application. In this article, we will delve into the possible causes of this error and provide a step-by-step guide to troubleshoot and resolve it.

The error message "I.streamCompletion(...) is not a function or its return value is not async iterable" indicates that the streamCompletion method is not recognized or is not returning an async iterable. This method is typically used to handle the completion of a stream, such as a response from an LLM. To better understand the issue, let's break down the possible causes:

  • Missing or incorrect method signature: The streamCompletion method might be missing or have an incorrect signature, which prevents it from being recognized.
  • Async iterable issue: The return value of the streamCompletion method might not be an async iterable, causing the error.
  • LLM client compatibility: The issue might be specific to the Ollama LLM client, which could be causing the error.

To resolve the "I.streamCompletion(...) is not a function or its return value is not async iterable" error, follow these steps:

Step 1: Verify the Method Signature

Check the documentation of the LLM client you are using to ensure that the streamCompletion method exists and has the correct signature. If the method is missing or has an incorrect signature, update your code accordingly.

Step 2: Check the Return Value

Verify that the return value of the streamCompletion method is an async iterable. You can do this by logging the return value or using a debugger to inspect it. If the return value is not an async iterable, update your code to handle it correctly.

Step 3: Ensure LLM Client Compatibility

As mentioned earlier, the issue might be specific to the Ollama LLM client. Try using a different LLM client to see if the error persists. If the error disappears with a different client, it's likely a compatibility issue with Ollama.

Step 4: Update Your Code

If the issue is specific to the Ollama LLM client, update your code to handle the streamCompletion method correctly. You can do this by using a different method or implementing a custom solution.

Step 5: Consult the Documentation

Refer to the documentation of the LLM client you are using to see if there are any known issues or workarounds for the streamCompletion method. The documentation might provide valuable insights or solutions to the problem.

Here's an example use case that demonstrates how to handle the streamCompletion method correctly:

import { LLMClient } from 'ollama';

const llmClient = new LLMClient('your-api-key');

async function handleStreamCompletion(stream) {
    try {
        const completion = await streamCompletion(stream);
        console.log(completion);
    } catch (error) {
        console.error(error);
    }
}

// Create a new stream
const stream = await llmClient.createStream('your-stream-name');

// Handle the stream completion
handleStreamCompletion(stream);

In this example, we create a new stream using the createStream method and then handle the stream completion using the handleStreamCompletion function. The handleStreamCompletion function uses the streamCompletion method to handle the completion of the stream and logs the result to the console.

The "I.streamCompletion(...) is not a function or its return value is not async iterable" error can be frustrating, especially when other LLM clients work seamlessly with your application. By following the troubleshooting steps outlined in this article, you should be able to resolve the issue and get your application working with the Ollama LLM client. Remember to verify the method signature, check the return value, ensure LLM client compatibility, update your code, and consult the documentation to resolve the issue.
I.streamCompletion(...) is not a function or its return value is not async iterable: Troubleshooting Guide

Q: What is the streamCompletion method and why is it causing an error?

A: The streamCompletion method is used to handle the completion of a stream, such as a response from an LLM. The error "I.streamCompletion(...) is not a function or its return value is not async iterable" indicates that the method is not recognized or is not returning an async iterable.

Q: Why is the error specific to the Ollama LLM client?

A: The issue might be specific to the Ollama LLM client due to compatibility issues. Try using a different LLM client to see if the error persists.

Q: How can I verify the method signature of the streamCompletion method?

A: Check the documentation of the LLM client you are using to ensure that the streamCompletion method exists and has the correct signature. If the method is missing or has an incorrect signature, update your code accordingly.

Q: What is an async iterable and why is it important?

A: An async iterable is a type of iterable that returns an asynchronous iterator. It's essential to ensure that the return value of the streamCompletion method is an async iterable to avoid the error.

Q: How can I check the return value of the streamCompletion method?

A: You can log the return value or use a debugger to inspect it. If the return value is not an async iterable, update your code to handle it correctly.

Q: What are some common causes of the "I.streamCompletion(...) is not a function or its return value is not async iterable" error?

A: Some common causes of the error include:

  • Missing or incorrect method signature
  • Async iterable issue
  • LLM client compatibility issue

Q: How can I update my code to handle the streamCompletion method correctly?

A: You can update your code to handle the streamCompletion method correctly by using a different method or implementing a custom solution.

Q: Where can I find more information about the streamCompletion method and its usage?

A: Refer to the documentation of the LLM client you are using for more information about the streamCompletion method and its usage.

Q: Can I use a different LLM client to resolve the issue?

A: Yes, you can try using a different LLM client to see if the error persists. If the error disappears with a different client, it's likely a compatibility issue with Ollama.

Q: How can I ensure that my code is compatible with the Ollama LLM client?

A: To ensure that your code is compatible with the Ollama LLM client, follow these best practices:

  • Verify the method signature of the streamCompletion method
  • Check the return value of the streamCompletion method
  • Ensure LLM client compatibility
  • Update your code to handle the streamCompletion method correctlyConclusion ==============
