NWBPM - Aggregator Pattern

Hi Experts,

I am working on NWBPM Aggregator Pattern..... I deployed it on PI server and while trying to START the PROCESS from the process repository I am getting below error -

Error -

Process 'Aggregator' set to In Error

A technical error occured during invocation of operation 'getTime' of interface 'SampleTimer': 'Could not invoke service reference name 245b832e-1ffe-4d3a-800a-5b1baf2f64fa, component name demo.sap.com~agg_rash~BPMcomponent, application name demo.sap.com/agg_rash.'.
