Using a text embedding model locally with semantic kernel

I've been reading Stephen Toub's blog post about building a simple console-based .NET chat application from the ground up with semantic-kernel. I'm following the examples but instead of OpenAI I want to use microsoft Phi 3 and the nomic embedding model. The first examples in the blog post I could recreate using the semantic kernel huggingface plugin. But I can't seem to run the text embedding example.

I've downloaded Phi and nomic embed text and are running them on a local server with lm studio.

Here's the code I came up with that uses the huggingface plugin:

using System.Net;
using System.Text;
using System.Text.RegularExpressions;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.SemanticKernel;
using Microsoft.SemanticKernel.Embeddings;
using Microsoft.SemanticKernel.Memory;
using System.Numerics.Tensors;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.SemanticKernel.ChatCompletion;

        // Initialize the Semantic kernel
        IKernelBuilder kernelBuilder = Kernel.CreateBuilder();
        kernelBuilder.Services.ConfigureHttpClientDefaults(c => c.AddStandardResilienceHandler());
        var kernel = kernelBuilder
            .AddHuggingFaceTextEmbeddingGeneration("nomic-ai/nomic-embed-text-v1.5-GGUF/nomic-embed-text-v1.5.Q8_0.gguf",
            new Uri("http://localhost:1234/v1"),
            apiKey: "lm-studio",
            serviceId: null)
            .Build();

        var embeddingGenerator = kernel.GetRequiredService<ITextEmbeddingGenerationService>();
        var memoryBuilder = new MemoryBuilder();
        memoryBuilder.WithTextEmbeddingGeneration(embeddingGenerator);
        memoryBuilder.WithMemoryStore(new VolatileMemoryStore());
        var memory = memoryBuilder.Build();
        // Download a document and create embeddings for it
        string input = "What is an amphibian?";
        string[] examples = [ "What is an amphibian?",
                              "Cos'è un anfibio?",
                              "A frog is an amphibian.",
                              "Frogs, toads, and salamanders are all examples.",
                              "Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia.",
                              "They are four-limbed and ectothermic vertebrates.",
                              "A frog is green.",
                              "A tree is green.",
                              "It's not easy bein' green.",
                              "A dog is a mammal.",

                              "Rachel, Monica, Phoebe, Joey, Chandler, Ross"];
        for (int i = 0; i < examples.Length; i++)
            await memory.SaveInformationAsync("net7perf", examples[i], $"paragraph{i}");
        var embed = await embeddingGenerator.GenerateEmbeddingsAsync([input]);
        ReadOnlyMemory<float> inputEmbedding = (embed)[0];
        // Generate embeddings for each chunk.
        IList<ReadOnlyMemory<float>> embeddings = await embeddingGenerator.GenerateEmbeddingsAsync(examples);
        // Print the cosine similarity between the input and each example
        float[] similarity = embeddings.Select(e => TensorPrimitives.CosineSimilarity(e.Span, inputEmbedding.Span)).ToArray();
        similarity.AsSpan().Sort(examples.AsSpan(), (f1, f2) => f2.CompareTo(f1));
        Console.WriteLine("Similarity Example");
        for (int i = 0; i < similarity.Length; i++)
            Console.WriteLine($"{similarity[i]:F6}   {examples[i]}");
    }
}

At the line:

for (int i = 0; i < examples.Length; i++)
    await memory.SaveInformationAsync("net7perf", examples[i], $"paragraph{i}");

I get the following exception:

JsonException: The JSON value could not be converted to Microsoft.SemanticKernel.Connectors.HuggingFace.Core.TextEmbeddingResponse

Does anybody know what I'm doing wrong?

I've downloaded the following nuget packages into the project:
