I am getting this error message using Azure when combining the LLM using the the langchain azure chat open ai clas: Failed to convert text into a pydantic model due to the following error: litellm.APIError: AzureException APIError - argument of type ‘NoneType’ is not iterable Using raw output instead.

I also had the same problem, still couldn’t find the fix ---

I fixed it by having to do this: ```auto os.environ["OPENAI_API_KEY"] = os.getenv("AZURE_OPENAI_KEY_openai_4o") os.environ["AZURE_API_KEY"] = os.getenv("AZURE_OPENAI_KEY_openai_4o") os.environ["AZURE_API_BASE"] = os.getenv("AZURE_OPENAI_ENDPOINT_openai_4o") os.environ["AZURE_API_VERSION"] = "2024-02-01" llm = LLM( model="azure/gpt-4o", ) ``` I do not understand why I cannot feed as arguments directly in LLM() instance. It is what it is… this is version of `crewai==0.79.4` ---

You can also use the **agents.yaml** file to instantiate the model and save the **env variables** in **.env** file in root folder. Example **.env** file: ```env AZURE_API_KEY=your-api-key-here # Replace with KEY1 or KEY2 AZURE_API_BASE=https://example.openai.azure.com/ # Replace with your endpoint AZURE_API_VERSION=2024-08-01-preview # API version ``` Then modify the **agents.yaml** to include the **llm** like so: ```yaml researcher: role: > {topic} Senior Data Researcher goal: > Uncover cutting-edge developments in {topic} backstory: > You're a seasoned researcher with a knack for uncovering the latest developments in {topic}. Known for your ability to find the most relevant information and present it in a clear and concise manner. llm: azure/gpt-4o-mini reporting_analyst: role: > {topic} Reporting Analyst goal: > Create detailed reports based on {topic} data analysis and research findings backstory: > You're a meticulous analyst with a keen eye for detail. You're known for your ability to turn complex data into clear and concise reports, making it easy for others to understand and act on the information you provide. llm: azure/gpt-4o-mini # replace with your deployed model from Azure ``` ---

what if i dont use yaml file? not everyone is using that latest configuration… you mentioned this is need to set in azure openai, but i took it “out of the box” didn’t do any change there. they are indicating different end points which is also confusing button line i can connect to azure openai when using crewai ---

Here’s an example without the YAML config. **1. Set `env` varibales** ```bash export AZURE_API_KEY="your-api-key" export AZURE_API_BASE="https://your-endpoint.openai.azure.com/" export AZURE_API_VERSION="2024-08-01-preview" ``` **2. Code** ```Python from crewai import Agent, Task, Crew, Process, LLM from crewai_tools import SerperDevTool import os # Configure the LLM to use Azure OpenAI azure_llm = LLM( model="azure/gpt-4o-mini", api_key=os.environ.get("AZURE_API_KEY"), # Replace with KEY1 or KEY2 base_url=os.environ.get("AZURE_API_BASE"), # example: https://example.openai.azure.com/ api_version=os.environ.get("AZURE_API_VERSION"), # example: 2024-08-01-preview ) # Agent definition researcher = Agent( role='{topic} Senior Researcher', goal='Uncover groundbreaking technologies in {topic} for year 2024', backstory='Driven by curiosity, you explore and share the latest innovations.', tools=[SerperDevTool()], llm=azure_llm ) # Define a research task for the Senior Researcher agent research_task = Task( description='Identify the next big trend in {topic} with pros and cons.', expected_output='A 3-paragraph report on emerging {topic} technologies.', agent=researcher, ) def main(): # Forming the crew and kicking off the process crew = Crew( agents=[researcher], tasks=[research_task], process=Process.sequential, verbose=True ) result = crew.kickoff(inputs={'topic': 'AI Agents'}) print(result) if __name__ == " __main__": main() ``` ---
