Azure OpenAI: DeploymentNotFound: The API deployment for this resource does not exist

I am using AzureOpenAI Service, and I just encountered an issue openai.NotFoundError: Error code: 404 - {'error': {'code': 'DeploymentNotFound', 'message': 'The API deployment for this resource does not exist. If you created the deployment within the last 5 minutes, please wait a moment and try again.'}}.

A quick Python example is attached here (need to first pip install openai and export the Azure-related environment variables).

import os
from openai import AzureOpenAI

AZURE_OPENAI_API_KEY = os.getenv("AZURE_OPENAI_API_KEY")
AZURE_OPENAI_ENDPOINT = os.getenv("AZURE_OPENAI_ENDPOINT")
client = AzureOpenAI(
    api_version="2024-02-01",
    api_key=AZURE_OPENAI_API_KEY,
    azure_endpoint=AZURE_OPENAI_ENDPOINT,
)

_tmp_messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "How many 'r's in strawberry?"}
]

_tmp_completion = client.chat.completions.create(
    model="gpt-4o-full",
    max_tokens=8192,
    messages=_tmp_messages,
)

print(_tmp_completion.choices[0].message.content)

Previously, this code worked well under my account. And I checked the billing there is no issue. I also tried out the AI Foundry (https://ms.portal.azure.com/#home), and it didn't work either, returning a similar error:

DeploymentNotFound: The API deployment for this resource does not exist. If you created the deployment within the last 5 minutes, please wait a moment and try again. | Apim-request-id: xxxxxxxx

Is there anyone who knows how to fix it? Thanks for your help!
