@AwesomeYuer Qdrant definition for Points object allows for both 64-bit integers and UUID strings

You can look at the ExtendedPointId object here:
https://github.com/qdrant/qdrant/blob/master/src/common/points.rs

@tawalke Thanks for your feedback in advance.
I think it would be better to support both int id and string uuid when deserializing as a string Id property from JSON.

Here is some sample code for reference, I have test it passed and succeed when invoke
QdrantVectorDbClient.FindNearestInCollectionAsync :

good

[craigomatic]

Another simple option we can consider:

[JsonPropertyName("id")]
[JsonNumberHandling(JsonNumberHandling.WriteAsString)]
public string Id { get; }
