Format exception when using culture and partitionKey, difference between Windows and Linux

Describe the bug We see different behavior between running queries on Linux versus Windows, when using culture Info and partition key/cross-partition key queries.

To Reproduce

using Microsoft.Azure.Cosmos.Fluent;
using Microsoft.Azure.Cosmos;
using Newtonsoft.Json;

namespace ConsoleApp1;

internal class Program
{
    static void Main(string[] args)
    {
        var client = new CosmosClientBuilder("---url---", "---key---").Build();
        var container = client.GetContainer("--database--", "--container--");

        Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");

        // Retrieves data
        var noCultureWithPartitionKey = container.GetItemLinqQueryable<QueryObject>(true, null, new QueryRequestOptions() { PartitionKey = new PartitionKey("bc7df108-4c93-4534-ba32-167d77274511") })
            .Where(c => c.Area > 5.65252);
        Console.WriteLine(noCultureWithPartitionKey.Count());

        // Retrieves data, cross partition
        var noCultureNoPk = container.GetItemLinqQueryable<QueryObject>(true, null, new QueryRequestOptions() { PartitionKey = null })
            .Where(c => c.Area > 5.65252);
        Console.WriteLine(noCultureNoPk.Count());

        // Change the culture
        Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("fr-FR");

        // Throws error
        try
        {
            var withCultureWithPartitionKey = container.GetItemLinqQueryable<QueryObject>(true, null, new QueryRequestOptions() { PartitionKey = new PartitionKey("bc7df108-4c93-4534-ba32-167d77274511") })
                .Where(c => c.Area > 5.65252);
            Console.WriteLine(withCultureWithPartitionKey.Count());
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

        // Same query, cross partition
        var withCultureNoPk = container.GetItemLinqQueryable<QueryObject>(true, null, new QueryRequestOptions() { PartitionKey = null })
            .Where(c => c.Area > 5.65252);
        Console.WriteLine(withCultureNoPk.Count());
    }
}

class QueryObject{

    [JsonProperty("id")]
    public string Id{ get; set; }

    [JsonProperty("partitionKey")]
    public string PartitionKey { get; set; }

    [JsonProperty("area")]
    public double Area{ get; set; }
}

Results on Windows:

Results on Linux:

Input string was not in a correct format.

Expected behavior Same behavior when running on Windows/Linux/Docker, independent on the thread culture.

Actual behavior We are running a docker container with an webapi which uses request localization based on the accept language header. Customers from Norway, France are running into problems, because of the “Input string was not in a correct format.” exception (all our queries are on a specific partition key).

Environment summary SDK Version: 2.32.3 OS Version Windows vs Linux (Ubuntu) vs Official Docker images

Additional context Add any other context about the problem here (for example, complete stack traces or logs).

This looks like the correct diagnosis. I’ll get this issue assigned. Thanks @mlankamp
