ParitionKey extracted from document doesn't match the one specified in the header - C#

I'm new to CosmosDB and trying to figure out what's going on. I am using Microsoft.Azure.Cosmos NuGet package for development.

This is the line that creates my container:

Container = await database.CreateContainerIfNotExistsAsync(Program.ContainerId, "/id", 400)

This is my class:

     public class REProperty
     {
        public const string PartitionKey = "id";

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

        public string Number { get; set; }

        public User Owner { get; set; }

And finally the code where I try to create a new document:

ItemResponse<REProperty> Response = await Program.Container.CreateItemAsync<REProperty>(C, new PartitionKey(REProperty.PartitionKey));

I am using the exact same PartitionKey everywhere yet I am still getting this error every time. Am I missing anything obvious?

Error message: (Message: {"Errors":["PartitionKey extracted from document doesn't match the one specified in the header"]

You've defined the collection to use the id property as the partition key. The value given as id will then be the partition key used. However, you are specifying this:

ItemResponse<REProperty> Response = await Program.Container.CreateItemAsync<REProperty>(C, new PartitionKey(REProperty.PartitionKey));

This will always set the value "id" as the partition key, which is not correct. The actual value is different from document to document. So either you set it like this: new PartitionKey(C.Id) or you just omit the partition key part in the item creation - I think it should be enough to just have the property set, but give it a try to check it.
