vROPS CASA api implentation gives CasaException and 500 Internal Server Error

Hi,

I ran the rest API of vROPS in rest client which is a CaSA API to configure slice name in vROPS

I got the 500 Internal Error with the error message as follows:

{"error_message_key":"general.failure","error_arguments":["com.vmware.vcops.casa.exception.CasaException: Update slice info failed"]}

Any help to solve this error is appreciated

Thanks
