[Question] Assigning the PartitionKey

Hi

I am trying to use this package configuring the custom partition key (/userIdentifier) instead of /Id, but I am getting an error from cosmos client as below System.ArgumentException: The requested partition key path '/id' does not match existing Container 'VideoElapsedTimeData' with partition key path '/userIdentifier' (Parameter 'PartitionKey')

public class VideoElapsedTimeData : Item
    {
        [JsonProperty("userIdentifier")] public string UserIdentifier { get; set; }
        [JsonProperty("consumedTimeInMs")] public double ConsumedTimeInMs { get; set; }
        [JsonProperty("metadata")] public string Metadata { get; set; } = string.Empty;
        [JsonProperty("videoType")] public string VideoType { get; set; } = string.Empty;
        [JsonProperty("viewedPercentage")] public double ViewedPercentage { get; set; }
        [JsonProperty("trimInMs")] public double TrimInMs { get; set; }
        [JsonProperty("trimOutMs")] public double TrimOutMs { get; set; }
        [JsonProperty("timestamp")] public DateTimeOffset Timestamp { get; set; } = DateTimeOffset.UtcNow;

        [JsonProperty("videoId")] public string VideoId { get; set; }

        protected override string GetPartitionKeyValue() => UserIdentifier;
    }

My container partition key set as /userIdentifier

Probably I am missing something I would be so glad if you could help, please.

Thank you

Yes, it’s working now. I have managed to solve it only after focusing on the source documentation. Would be nice to have an example though. Great job, thanks.

There is no reason to implement your own IItem, in this case just use the provided Item which already exposes the functionality you’re looking for and override the Item.GetPartitionKeyValue().
