I'm testing my first embed from firebase but the text content throws an error

Hi all! Completely new to this and chugging through a test fixing errors along the way, but stumped by this one.

I’m testing a Firebase cloud function to backfill embeds on one of my tables (so I can see how to use genai on my own data).

It pulls the data fine and iterates through all of the documents, but it doesn’t like something about the ‘content:’ part of the embedContents call and I have no idea what. :frowning:

Now, you can see some of the data below, and maybe this won’t actually do anything useful from the perspective of interfacing with the database, but at this point I want to understand what’s wrong so I can test and see. Thanks in advance for any help!

Update: I guess the question is really, what is wrong with this text string that embedContent doesn’t recognize it as a valid ‘content:’?

“0 1 59 Strength Mental Conditioning Firebreathing Finisher Squat 0 0 50 Weight Reps Distance Time Calories Movement Scaled Rx Competition Strongman 0 0 Quads Hamstrings Glutes 0 0 Yoke Core 0 Weight plates bumper plates 0 Yoke 0 0 Squat”

Code:
const MODEL_NAME = “gemini-embedding-001”;
const genAI = new GoogleGenerativeAI(GEM_API_KEY);
.
. <setting up firebase connection, pulling data, etc>
.
const textToEmbed = extractTextFromDocument(docData);

  if (!textToEmbed) {
    console.log(`No text found in document ${docId} to generate an embedding. Skipping.`);
    continue; // Move to the next document
  }

  try {
    // Generate the embedding
    const result = await model.embedContent({
      content: textToEmbed,
    } );

    // previous:  const result = await model.embedContent({parts: [{text: textToEmbed}]});
    // ex:    contents: [{role: "user", parts: [{text: prompt}]}],
    const embedding = result.embedding.values;

Here’s the error (note that some of this has been removed because I needed to break the links as a new poster limited to 2 links):
