Unable to read edges from Cosmos DB

[mihirrane-wb]

I used the code provided to write the data into Cosmos DB. I had written vertices with different labels into Cosmos DB
cosmosDbVertices.write.format(cosmosDbFormat).mode("append").options(**cosmosDbConfig).save() cosmosDbEdges.write.format(cosmosDbFormat).mode("append").options(**cosmosDbConfig).save()
I was successful in doing so using the Cosmos OLTP library. I can see the vertices and edges in Cosmos DB when I checked using the Azure Portal.The problem arises when I try to read - I can only see these columns
id:string
label:string
element:struct
id:string
_value:string
I am not getting columns _isEdge, _sink and _vertexId.
