Langchain OpenAIEmbeddings resource not found (404) with AzureOpenAI credentials

I'm having trouble using LangChain embedding with Azure OpenAI credentials - it's showing a 404 error for resource not found.

stack trace: Error: 404 Resource not found
    at APIError.generate (c:\abcproject\node_modules\openai\error.js:53:20

import { OpenAIEmbeddings } from "@langchain/openai"

export const embeddingModel = new OpenAIEmbeddings({ 
  azureOpenAIApiKey: "AzureOpenAI api key",
  azureOpenAIApiVersion: "2023-08-01-preview",
  azureOpenAIApiDeploymentName: "gpt-4-32k",
  azureOpenAIBasePath:"Azure OpenAI endpoint"
});
Solution

  • The definition of your OpenAIEmbeddings class is incorrect: you should not have something related to gpt models for embeddings, but "text-embedding-ada-002" instead.

    Try modifying your azureOpenAIApiDeploymentName value or better use modelName (see doc)
