Cosmos DB V2 Connector doesn't load json arrays

[sittell]

Hi, 

I'm trying to build Power BI reports on top of Cosmos DB using Cosmos DB V2 Connector and a Direct Query Mode. Currently I have an issue with json data which contains arrays. In this case when loading the data, arrays are shown as a separate table which has been evaluating and never being loaded. All other data has been loaded sucessfully, but has a column with a link to the array as a table which doesn't work. Has anyone had the same problem and has an idea how it could be solved? Is there any way to work with arrays with Cosmos DB V2 Connector for Power BI or you have to create some data preparation in between?

I've read this topic, but it doesn't really suggest any solution.

I would be grateful for any feedback!

Best regards,

Lisa

Hi Liu, 

Thank you for your feedback! Is there any way to specify an sql query for Cosmos DB V2 connector in order to flatten Cosmos DB data?

Thanks.
