ValidationError: 1 validation error for VertexAI

Checked other resources

• [X] I added a very descriptive title to this issue.
• [X] I searched the LangChain documentation with the integrated search.
• [X] I used the GitHub search to find a similar question and didn't find it.
• [X] I am sure that this is a bug in LangChain rather than my code.

Example Code

# Generate summaries of text elements
def generate_text_summaries(texts, tables, summarize_texts=False):
    """
    Summarize text elements
    texts: List of str
    tables: List of str

    # Prompt
    prompt_text = """You are an assistant tasked with summarizing tables and text for retrieval. \
    These summaries will be embedded and used to retrieve the raw text or table elements. \
    Give a concise summary of the table or text that is well-optimized for retrieval. Table \
    or text: {element} """
    prompt = PromptTemplate.from_template(prompt_text)
    empty_response = RunnableLambda(
        lambda x: AIMessage(content="Error processing document")
    )
    # Text summary chain
    model = VertexAI(
        temperature=0, model_name="gemini-pro", max_output_tokens=1024
    ).with_fallbacks([empty_response])
    summarize_chain = {"element": lambda x: x} | prompt | model | StrOutputParser()

    # Initialize empty summaries
    text_summaries = []

    # Apply to text if texts are provided and summarization is requested
    if texts and summarize_texts:

Hey there, @andysingal! Nice to see you back in the world of coding conundrums. Hope you've been well since our last tech adventure.

The error message you're seeing is indicating that the VertexAI instance is unable to find your Google Cloud project. This is likely because you haven't set your project ID in the environment where your code is running.

Here are the steps to set up your Google Cloud project:

1. Create a Google Cloud project: If you haven't already, you'll need to create a Google Cloud project. You can do this by following the instructions here.

2. Set your project ID: Once you have a project, you'll need to set your project ID in your environment. You can do this in several ways:

   • Passing a constructor argument: When you instantiate the VertexAI class, you can pass your project ID as an argument. For example:

     model = VertexAI(
      temperature=0, 
      model_name="gemini-pro", 
      max_output_tokens=1024, 
      project_id="your-project-id"
     )

   • Using vertexai.init(): You can call the vertexai.init() function and pass your project ID. For example:

     vertexai.init(project_id="your-project-id")

   • Setting project using 'gcloud config set project': If you have the Google Cloud SDK installed, you can set your project ID using the gcloud command-line tool. For example:

     gcloud config set project your-project-id

   • Setting a GCP environment variable: You can set your project ID as an environment variable. The name of the variable should be GOOGLE_CLOUD_PROJECT. For example:

     export GOOGLE_CLOUD_PROJECT=your-project-id

Replace "your-project-id" with the ID of your Google Cloud project.

3. Authenticate your Google Cloud account: If you haven't already, you'll need to authenticate your Google Cloud account. You can do this using the gcloud command-line tool. For example:

   gcloud auth login

After following these steps, your VertexAI instance should be able to find your Google Cloud project and the error should be resolved. If you're still encountering issues, please provide more details about your environment and the steps you've taken so far.
