Inserting vectors in Xata results in Bulk operation failed error

[codenameakshay]

I am using "langchain": "^0.0.150", and "@xata.io/client": "^0.27.0". So when I import the xata client and create a vector store from it

    // Fetch vector store
    this.vectorStore = new XataVectorSearch(new OpenAIEmbeddings(), {
      client: this.client(),
      table: 'articles',
    });

and I try to call addVectors or addDocs method like this ->

vectorStore.addVectors(embeddings, docs);
// vectorStore.addDocs(docs);

I get this error ->

Error: Bulk operation failed

It says the error is in this line 66 in xata.cjs but I am not able to debug what went wrong.

Even if I try to add a single doc it fails with the same error. I have tried to add docs through Postman calling Xata APIs and it works. Not sure why it is failing here though.

Hello @codenameakshay,

I'm here to assist you with your issues and inquiries related to the langchainjs repository. I'm an AI bot and can help guide you through bug fixes, answer your questions, and help you become a contributor. While we wait for a human maintainer, feel free to ask me any questions you might have. I'm here to help!

The "Bulk operation failed" error you're encountering could be due to a variety of reasons. Here are a few potential causes:

1. Data Size: If the size of the data you're trying to add exceeds the limit allowed by the Xata database, it could result in a bulk operation failure.

2. Data Format: The data you're trying to add might not be in the correct format. The addVectors method expects an array of vectors and an array of documents. If the data doesn't match this format, it could lead to an error.

3. Database Connection: There might be an issue with the connection to the Xata database. If the connection is unstable or lost during the operation, it could result in a failure.

4. Database Constraints: The Xata database might have certain constraints or rules that are being violated by the operation, resulting in a failure.

5. API Limitations: If you're making too many requests to the Xata API in a short period of time, it might rate limit your requests, resulting in a failure.

Without more specific information about the error and the context in which it's occurring, it's difficult to provide a more precise answer. Could you please provide more details about the data you're trying to add (size, format, etc.) and the exact steps you're following when the error occurs? This will help in diagnosing the issue more accurately.

Okay I was able to find out the problem, one of my column on xata had type mismatch. But it should've thrown that error, instead I had to manually one by one check which column has issue, as it just says Bulk operation failed.
