Oracle Backup Cloud Assistant bkup_api - API::ERROR KBHS-00715: HTTP error occurred 'oracle-error'

When trying to take Oracle Database Cloud Backup using Cloud Backup AssistantI got the below errors.

Error:

-> API::ERROR  KBHS-00715 HTTP CONNECTION ERROR

 -> API::ERROR -Detail

 -> API::ERROR KBHS-00715: HTTP error occurred 'oracle-error'

 -> API::ERROR OBKUP:: ..... FAIL

 -> API::ERROR ORA-19511: non RMAN, but media manager or vendor specific failure, error text:

 -> API::ERROR ORA-19554: error allocating device, device type: SBT_TAPE, device name:

 -> API::ERROR ORA-27023: skgfqsbi: media manager protocol error

After some digging realized that this is a known issue with Oracle Cloud Backup  Assistant.
