Would you try the dedicated server? serverless may have some problem on langchain.js. it needs to be update.

Got you, dedicated server works. Looking forward to the serverless update. 💪

Hi there, any updates or further guides on the server side?

I've noticed and tried latest milvus client update on langchain-js, still not working w/ serverless server. :(

@webup Hi, we update example now. Please have a check.

I've updated langchain and milvus lib to the latest, and followed this ut as the sample which should be same as your langchain.js sample, but still failed to connect the server.

  new OpenAIEmbeddings(),
  {
    collectionName: "langchain_valtown",
    // autoId: false,
    // primaryField: "id",
    clientConfig: {
      address: process.env.ZILIZ_URL,
      token: process.env.ZILIZ_API_KEY,
      ssl: true,
    },
  }

Following error messages returned:
