FTP OSA format output using AIS call

Hi All,

I am trying to ftp the report output in OSA format, AIS calls fails for OSA viewtype. Orchestration AIS documents shows that it supports the OSA format but it throws null pointer exception and for viewtype PDF it works fine.

External Orchestration -URL http://server/jderest/v2/report/execute 

External Orchestration - Response Contents  ExternalRestService - generic httpRequest() Failure - HTTP Request java.lang.Exception: External Generic Call Failed See Log For Details: 500 {"exception":"NullPointerException","timeStamp":"2022-09-19T14:27:52.316-0400"}

Thanks.
