wanted to Create Re-occurence of Workflow

Hello,

I wanted to create a mechanism which run every hour, which maintain my workflow should be running all the time, if in case it is not running that mechanism check for it and start workflow again.

I do not want to schedule the workflow because it does not check if the current workflow is in running mode or not, it will simply execute another instance of it.

I think creating Policy which run every hours, should address this but since i don't know scripting much, i am unable to design this mechanism.

I wanted to have Policy check for Workflow Token against workflow ID and based upon token state, it should decide to execute or not. I had written something but still not sure if this is correct or what should i modify to make it working..Although not complete

var wfId = "d762a53e-fbdb-408d-8d8d-f6ee44b913ed";

System.log(wfId);

var token = WorkflowToken(wfId);

System.log(token);

System.log("Launching Automated horizontal Scaling Workflow: " + wfId);

wfId.execute();

System.log(wfToken);

System.log("startDate: " + token.startDate);

System.log("state: " + token.state);

While in logs i am getting below
