Embedding in TextNode show undefined

[myhendry]

hi, I am new to llamaindex.

i configure my Settings.embedModel as such:

 Settings.embedModel = new OpenAIEmbedding({
    apiKey: process.env.OPENAI_API_KEY,
    model: "text-embedding-ada-002",
  });

however, in my TextNode, i am seeing embedding undefined in my TextNode. is this the correct behavior? are my docs in llamaindex ts embedded since I have already set the embedModel as OpenAIEmbedding?
