ChromaDB.Client.ChromaException: Unexpected status code: MethodNotAllowed.

[hannahhaken]

I have installed 1.0.0 of the SDK and this is the code I have implemented:

        var configOptions = new ChromaConfigurationOptions(uri: chromaUri);
        using var httpClient = new HttpClient();
        var chromaClient = new ChromaClient(configOptions, httpClient);
        
        var collection = await chromaClient.GetOrCreateCollection(collectionName);
        return new ChromaCollectionClient(collection, configOptions, httpClient);

When I run the code with a collection name against chromadb/chroma:1.0.3 running locally in Docker, I get the following error:

Unhandled exception. ChromaDB.Client.ChromaException: Unexpected status code: MethodNotAllowed.
   at ChromaDB.Client.Common.HttpClientHelpers.Send[TResponse](HttpClient httpClient, HttpRequestMessage httpRequestMessage)
   at ChromaDB.Client.Common.HttpClientHelpers.Post[TInput,TResponse](HttpClient httpClient, String endpoint, TInput input, RequestQueryParams queryParams)
   at ChromaDB.Client.ChromaClient.GetOrCreateCollection(String name, Dictionary`2 metadata, String tenant, String database)
   at ConsoleApp1.ChromeCollectionFactory.CreateAsync(String chromaUri, String collectionName) in /Users/hannahhaken/workarea/LLamaSharp/ConsoleApp1/ChromaConnector.cs:line 47
   at Program.<Main>$(String[] args) in /Users/hannahhaken/workarea/LLamaSharp/ConsoleApp1/Program.cs:line 11
   at Program.<Main>(String[] args)

Any idea what could be causing this?

There is a mismatch occuring. If you run in docker via:
docker run -v ./chroma-data:/data -p 8000:8000 chromadb/chroma

go to localhost:8000/docs and you'll notice they are all v2 api calls.

if you run pip install chromadb then "chroma run" you'll see v1 api calls in docs.

if you fiddler your application with this client, it just botches the call completely(if you look at the api docs).
POST http://localhost:8000/api/v1/collections?tenant=localtestTenant&database=localtestDb HTTP/1.1
