Hi I'm trying to add a source-engine to my meta-engine but having this error

I'm using the version shown below.

```auto
    "@elastic/app-search-node": "^7.12.0",

```

Can anyone let me know what I'm doing wrong here.

```auto
Error: Not Found
    at Request._callback (/home/ctp/git/nodejs-backend/node_modules/@elastic/app-search-node/lib/client.js:95:26)
    at Request.self.callback (/home/ctp/git/nodejs-backend/node_modules/request/request.js:185:22)

    at processTicksAndRejections (node:internal/process/task_queues:83:21) {
  errorMessages: ['Not Found']

```

```auto
const AppSearchClient = require("@elastic/app-search-node");
const private_key = process.env.elastic_private_key;
const search_key = process.env.elastic_search_key;
const baseUrlFn = () => " ";
const client = new AppSearchClient(undefined, private_key, baseUrlFn);

```

Here is my code.

```auto
const AppSearchClient = require("@elastic/app-search-node");
const private_key = process.env.elastic_private_key;
const search_key = process.env.elastic_search_key;
const baseUrlFn = () => "https://my-deployment-a685d4.kb.us-central1.gcp.cloud.es.io:9243/internal/app_search/engines";
const client = new AppSearchClient(undefined, private_key, baseUrlFn);

addSourceEng(metaName, source_engine) {
    client
      .addMetaEngineSources('all', [source_engine])

      .then((response) => console.log(response))
      .catch((error) => console.log(error))

  }

```

This looks too long. If you navigate to the "Credentials" tab in the App Search UI it should give you the correct base URL to use here.

I'm guessing it would be:
