Lỗi Thường Gặp Và Cách Khắc Phục

Lỗi 1: Lỗi xác thực API Key

========================================
LOI: "Invalid API key" hoac "401 Unauthorized"
========================================

NGUYEN NHAN:
- Sai API key
- Copy thua khoang trang
- Key da bi revoke

CACH KHAC PHUC:


1. Kiem tra lai API key

echo $HOLYSHEEP_API_KEY


2. Xoa khoang trang thua

export HOLYSHEEP_API_KEY="YOUR_HOLYSHEEP_API_KEY"


3. Kiem tra key con hop le khong

Lỗi 2: Rate Limit Error - Quá giới hạn request

========================================
LOI: "429 Too Many Requests" hoac "Rate limit exceeded"
========================================

NGUYEN NHAN:
- Qua nhieu request trong thoi gian ngan
- Vuot qua RPM/TPM cho tai khoan free

CACH KHAC PHUC:


1. Implement exponential backoff

import time
import openai

def call_with_retry(client, messages, max_retries=3):
    for attempt in range(max_retries):
        try:
            response = client.chat.completions.create(
                model="deepseek-chat-v3.2",
                messages=messages
            )
            return response
        except openai.RateLimitError:
            wait_time = 2 ** attempt  # 1s, 2s, 4s
            print(f"Cho {wait_time}s truoc khi thu lai...")
            time.sleep(wait_time)
    raise Exception("Qua so lan retry")


2. Su dung async queue cho batch processing

import asyncio

async def process_batch(messages_list):
    tasks = [
        call_with_retry(client, msg) 
        for msg in messages_list
    ]
    # Gioi han 10 request dong thoi
    results = await asyncio.gather(*tasks, return_exceptions=True)
    return results


3. Nang cap len goi cao hon


Dashboard: https://www.holysheep.ai/dashboard/usage

========================================

Lỗi 3: Timeout và Context Length

========================================
LOI: "Timeout" hoac "Maximum context length exceeded"
========================================

NGUYEN NHAN:
- Request qua lon (>200K tokens)
- Server bi overload
- Network latency cao

CACH KHAC PHUC:


1. Xu ly timeout

from openai import Timeout

response = client.chat.completions.create(
    model="deepseek-chat-v3.2",
    messages=messages,
    timeout=Timeout(60.0)  # 60 giay
)


2. Xu ly context length

MAX_CONTEXT = 180000  # De 20K cho output

def truncate_messages(messages, max_tokens=MAX_CONTEXT):
    total = sum(len(m['content']) for m in messages)
    if total > max_tokens:
        # Lay tin nhan gan nhat nhat
        while total > max_tokens and len(messages) > 1:
            removed = messages.pop(0)
            total -= len(removed['content'])
    return messages


3. Su dung streaming cho response dai

stream = client.chat.completions.create(
    model="deepseek-chat-v3.2",
    messages=messages,
    stream=True
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
========================================

Lỗi 4: Model Not Found

========================================
LOI: "Model 'xxx' not found"
========================================

NGUYEN NHAN:
- Ten model sai chinh ta
- Model khong con ho tro

CACH KHAC PHUC:


1. Lay danh sach model hien co

models = client.models.list()
for model in models.data:
    print(model.id)


2. Model name chinh xac

MODELS = {
    "deepseek": "deepseek-chat-v3.2",
    "gpt4": "gpt-4.1",
    "claude": "claude-sonnet-4.5",
    "gemini": "gemini-2.5-flash"
}


3. Kiem tra trang thai model
