'Specified method is not supported' runtime exception

I have seen this question before but i couldn't find a answer that helped my case, but somebody can probably find a way, so i came to ask here. When i run this code:

public static async Task<List<float>> GetEmbedding(string input, CancellationToken cancellationToken = default)
{
    string embeddingModel = "text-embedding-3-small";

    // Get GoogleAI
    GoogleAI googleAI = new(apiKey: "apikey");

    // Make the Generative model
    googleAI.GenerativeModel(embeddingModel);
    GenerativeModel model = googleAI.GenerativeModel(embeddingModel);

    // Embed the content
    EmbedContentResponse embedding = new EmbedContentResponse();
    try
    {
        embedding = await model.EmbedContent(input, embeddingModel);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }


    // Here i get error
    return embedding.Embedding.Values;
}

I get the 'Specified method is not supported' error, on the last line, but when i remove the try and catch, the error happens on this line: embedding = await model.EmbedContent(input, embeddingModel);

I am newer to GoogleAi, embeddings and vector databases, so its probably something i have overlooked.

I started by using breakpoints, but it just hits the error on that line. I have looked through another question but couldn't find an answer that would fit my application. Comment if you need more code :)

You may change your embeddingModel = “text-embedding-3-small” into these 9 Embeddings for Text supported model versions namely:

  • Text-embedding-preview-0815

  • Text-embedding-004

  • Text-multilingual-embedding-002

  • Text-embedding-preview-0409

  • Text-multilingual-embedding-preview-0409

  • textembedding-gecko@003

  • textembedding-gecko@002

  • textembedding-gecko-multilingua@001

  • textembedding-gecko@001
