Dremio -- multi sheet support

HI, I actually has a blob storage which has a multi sheet excel file. When i try to read data, it throws bad request.
POST call on
Request body:

Response i get back is
[no message for java.lang.NullPointerException]

I do not see much in the logs as well.

Could you provide an example file that exhibits this? Perhaps remove all the data so its safe to share.
