api/v1/namespace/du?path=/s3v/fso-bucket/dir1/key1-fso&files=true&sortSubPaths=true
{
"path": "/s3v/fso-bucket/dir1/key1-fso",

@smitajoshi12, thank you for working on this.

Could you please show us the error message that appeared earlier and how it is displayed in the UI after the fix?

@ArafatKhan2198 @devabhishekpal
I have added details in before patch as File Size and File Size Replication was missing for Entity Type= KEY

Hi @smitajoshi12,

I'm having trouble understanding the changes we've implemented here. Have we modified the response? The responses before and after the patch seem completely different. Could you please clarify what the behaviour was previously and what it is now?

Makes more sense now.
