Custom Json serializer options not respected in ImportDocuments

[cala-br]

Hi, we have a collection that has the fields written in snake case.

When registering the client, we provide a custom json serializer.

builder.Services.AddTypesenseClient(x =>
{
    x.ApiKey = typesenseOptions.ApiKey;
    x.Nodes =
    [
        new Node(
            host: typesenseOptions.Url.Host,
            port: typesenseOptions.Url.Port.ToString(),
            protocol: typesenseOptions.Url.Scheme
        )
    ];

    x.JsonSerializerOptions ??= new JsonSerializerOptions();
    x.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter());
    x.JsonSerializerOptions.PropertyNamingPolicy = JsonNamingPolicy.SnakeCaseLower;
});

While the methods that are used for reading (such as SearchInternal) use _jsonNameCaseInsensitiveTrue, and thus respect the custom json serializer options, the ImportDocuments method uses the _jsonOptionsCamelCaseIgnoreWritingNull.

This field, when set, overrides the custom options with -- as the name implies -- the CamelCase naming policy, thus making the import fail.

Line 57

typesense-dotnet/src/Typesense/TypesenseClient.cs

Lines 48 to 60 in f524cad

	if (config.Value.JsonSerializerOptions is not null)
	{
	_jsonNameCaseInsensitiveTrue = new JsonSerializerOptions(config.Value.JsonSerializerOptions)
	{
	PropertyNameCaseInsensitive = true
	};
	_jsonOptionsCamelCaseIgnoreWritingNull = new JsonSerializerOptions(config.Value.JsonSerializerOptions)
	{
	PropertyNamingPolicy = JsonNamingPolicy.CamelCase,
	DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingNull
	};
	}

Is this behavior intended?

As of now, we've managed to circumvent this problem by serializing the documents manually, and then passing them to the import method, but if feels a bit "dirty".

Same problem here. I was very confused why my PropertyNamingPolicy = JsonNamingPolicy.SnakeCaseLower was not working. Another workaround would be to manually specify [JsonPropertyName("")] for each property since this overrides the configured naming policy.
