Run Auto Predict Job through Groovy REST API call

Hey all,

I feel like I'm missing something obvious here. I'm attempting to write a Groovy rule that executes a REST API call to allow a lower permissions user to execute an Auto Predict job. I have the following and I'm getting a "Not Found" as my response even though the Auto Predict job is configured and saved.

Application app = operation.application
String appName = app.getName()


HttpResponse<String> jsonResponse = operation.application.getConnection('EPBCS_SELF_REST_TEST').post("/HyperionPlanning/rest/v3/${appName}/jobs")

.header("Content-Type", "application/json")

.body(json(["jobType":"Auto Predict","jobName":"FMO Prediction", "parameters":["forceRun": "true"]])).asString()

println jsonResponse.body
