Good evening, @roli-reeshik! I'm here to help you with any bugs, questions, or contributions you have. Let's tackle this together!

To resolve the "Error Building Component OpenAI: 1 validation error for ChatOpenAI root Did not find openai_api_key" issue, you need to ensure that the openai_api_key is provided when building the OpenAIModelComponent. The openai_api_key is a required field and must be supplied for the component to function correctly.

Here is the relevant part of the code where the openai_api_key is used:

def build(
        self,
        input_value: Text,
        openai_api_key: str,
        temperature: float,
        model_name: str,
        max_tokens: Optional[int] = 256,
        model_kwargs: NestedDict = {},
        openai_api_base: Optional[str] = None,
        stream: bool = False,
        system_message: Optional[str] = None,
    ) -> Text:
    if not openai_api_base:
        openai_api_base = "https://api.openai.com/v1"
    if openai_api_key:
        api_key = SecretStr(openai_api_key)
    else:
        api_key = None

    output = ChatOpenAI(
        max_tokens=max_tokens,
        model_kwargs=model_kwargs,
        model=model_name,
        base_url=openai_api_base,
        api_key=api_key,
        temperature=temperature,
    )

    return self.get_chat_result(output, stream, input_value, system_message)

Make sure that when you instantiate or configure the OpenAIModelComponent, you provide a valid openai_api_key. For example:

component = OpenAIModelComponent()
result = component.build(
    input_value="Your input text here",
    openai_api_key="your_openai_api_key_here",
    temperature=0.7,
    model_name="gpt-3.5-turbo",
    max_tokens=150,
    model_kwargs={},
    openai_api_base=None,
    stream=False,
    system_message=None
)

Replace "your_openai_api_key_here" with your actual OpenAI API key. This should resolve the validation error ^{[1][2][[3]](https://github.com/logspace-ai/langflow/blob/dev/src/backend/base/langflow/initial_setup/starter_projects/Langflow Blog Writter.json)}.

Additionally, you can set the openai_api_key as an environment variable named OPENAI_API_KEY:

1. In the OpenAI API Key field, click the Globe button to access environment variables, and then click Add New Variable.
2. In the Variable Name field, enter openai_api_key.
3. In the Value field, paste your OpenAI API Key (sk-...).
4. Click Save Variable.

Alternatively, you can configure environment variables in your .env file by setting LANGFLOW_STORE_ENVIRONMENT_VARIABLES to true. This will add all variables in LANGFLOW_VARIABLES_TO_GET_FROM_ENVIRONMENT to your user's Global Variables. The default list includes OPENAI_API_KEY among others ^{[4][5][6][7][8]}.
