I am running a simple Siddhi application as suggested on WSO2 documentation but I get the following exception. I'm following step 2 of this guide below https://ei.docs.wso2.com/en/latest/streaming-integrator/quick-start-guide/quick-start-guide/ Can someone Please tell me what I'm doing wrong? I have the productions.csv in
C:\Users\foo\productions.csv
