mongo-go-driver find a document by _id

Question

I\'m trying to find a document by its auto generated _id field. Code below returns nothing:

var documentID bson.RawValue
documentID.Type = 7
documentID.Value         


        

Answer 1

As @Carlos mentioned, I changed my code as this and everything works well.

objID, _ := primitive.ObjectIDFromHex("5c7452c7aeb4c97e0cdb75bf")
value := collection.FindOne(ctx, bson.M{"_id": objID})
