Hi!
I was trying out this API: https://pr-ark-codegen-1646.specs.preview.cogniteapp.com/v1.json.html#tag/Instances-(New)/operation/byExternalIdsInstances.

When i try to Retrieve a node by external id by giving source details as well, it works fine for a single View-ID pair. But when i try to do for more than one, I’m getting empty response.

Example: Say Id1 belongs to View1, and Id2 belongs to View2.
Querying with (Sources : View1, items : id1) as well as (Sources : View2, items : id2) gives correct response as expected. But when I try (Sources : [View1,View2], items : [id1,id2]), i get empty response. I was hoping it would provide information on both Id1 and Id2

 @Sangavi M , This API has changed.   https://docs.cognite.com/api/v1/#tag/Instances/operation/byExternalIdsInstances this is the most recent.  Can you have a look and see if this issue still exists for you.  If so, tag me and I can have a second look.
