What will you learn?

By diving into this tutorial, you will master the art of troubleshooting and resolving a 404 error that may arise during workload analysis with Locust on the OpenAI API GPT-3.5. You’ll gain insights into identifying the root cause of the issue and implementing effective solutions to ensure seamless workload analysis.

Introduction to Problem and Solution

When dealing with APIs such as OpenAI’s GPT-3.5 in conjunction with testing tools like Locust, encountering errors like the 404 status code is a common occurrence. The 404 error signifies that the server couldn’t locate the requested resource. In this guide, our objective is to pinpoint why this error occurs and provide strategies to conduct workload analysis smoothly without facing the 404 hurdle.

To tackle the 404 error during workload analysis using Locust on OpenAI API (GPT-3.5), it’s crucial to validate that your test scenarios are accurately configured, and your requests are directed towards the correct endpoints with valid parameters.


# Import necessary libraries
from locust import HttpUser, task, between

class MyUser(HttpUser):
    wait_time = between(1, 2)

    def analyze_workload(self):
        response = self.client.get("/your-endpoint-here")

        # Validate response status code
        if response.status_code == 200:
            print("Request successful!")
            print(f"Request failed with status code: {response.status_code}")

In this code snippet: – Define a MyUser class inheriting from HttpUser for HTTP requests. – The analyze_workload method sends a GET request to a specified endpoint (“/your-endpoint-here”). – Check if the response status code is 200 (indicating success) and print an appropriate message based on the result. – Running this script via Locust enables monitoring system behavior under load conditions while ensuring proper response handling.

    How can I debug a 404 error in my Locust test?

    To debug a 404 error in your Locust test, verify that you’re targeting the correct endpoint with valid parameters and inspect request headers along with payload data.

    Why am I receiving a 404 status code during workload analysis?

    A prevalent reason for encountering a 404 status code is requesting a resource or endpoint absent on your targeted server.

    Can network issues cause false-positive 404 errors in tests?

    Yes, network connectivity issues or server-side problems might lead to false-positive instances of receiving a 404 response during testing.

    Is using try-except blocks recommended for handling HTTP response exceptions?

    Indeed, employing try-except blocks aids in capturing exceptions related to HTTP responses like unexpected status codes such as 404 for graceful handling within test scripts.

    Should rate limiting or authentication issues be considered potential causes of receiving a 404 error?

    Certainly! Rate limiting policies by APIs or unmet authentication requirements can both trigger receiving a Not Found (404) response.


    In essence, resolving HTTP errors like “Error: Status Code – Not Found (HTTP/1.1 – RFC7231)” demands profound comprehension of API configurations coupled with meticulous examination of corresponding request payloads/response bodies through robust monitoring mechanisms integrated alongside comprehensive Performance/Load Tests.
