I encountered below NotFoundError when running langchain tutorial program (code: model.invoke(messages). Please help and advise, thanks.

NotFoundError: Error code: 404 - {'error': {'code': '404', 'message': 'Resource not found'}

LangChain tutorial program:


import os
os.environ["AZURE_OPENAI_API_KEY"] = "d957dxxxxxxxxxxxxxxxxxxxxxxxxx18438ba99f4b7"
os.environ["AZURE_OPENAI_ENDPOINT"] = "https://xxxxxxxxxx.cognitiveservices.azure.com/"
os.environ["AZURE_OPENAI_DEPLOYMENT"] = "Microsoft.CognitiveServicesAllInOne-20240775798778"
os.environ["AZURE_OPENAI_API_VERSION"] = "2021-04-30"

from langchain_openai import AzureChatOpenAI

model = AzureChatOpenAI(

    azure_deployment=os.environ["AZURE_OPENAI_DEPLOYMENT"],
    openai_api_version=os.environ["AZURE_OPENAI_API_VERSION"]

    Hi @Peter,

    Thank you for reaching out to Microsoft Q&A forum!

    I tried to repro the issue with the given code below and able to run the program:

    import os
    from langchain_openai import AzureChatOpenAI
    from langchain_core.messages import HumanMessage, SystemMessage
    
    # Set your Azure OpenAI credentials in environment variables
    os.environ["AZURE_OPENAI_API_KEY"] = "<KEY>"
    os.environ["AZURE_OPENAI_ENDPOINT"] = "https://<ENDPOINT>.openai.azure.com/" # Ensure this is correct
    os.environ["AZURE_OPENAI_DEPLOYMENT"] = "gpt-4o-mini" # Use your actual deployment name
    os.environ["AZURE_OPENAI_API_VERSION"] = "2023-05-15" # Check if this version is supported
    
    # Initialize the AzureChatOpenAI model
    model = AzureChatOpenAI(
        azure_endpoint=os.environ["AZURE_OPENAI_ENDPOINT"],
        azure_deployment=os.environ["AZURE_OPENAI_DEPLOYMENT"],
        openai_api_version=os.environ["AZURE_OPENAI_API_VERSION"]
    )
    
    # Create system and human messages
    messages = [
        SystemMessage(content="Translate the following from English into Italian"),
        HumanMessage(content="hi!")
    ]
    response = model.invoke(messages)
    
    # Print the translation
    print("Translation:", response)
    

    Output:
