Pentaho version 7.1 community edition fails to load the scripting engine for ECMAScript. How do I resolve the issue?

Question

I downloaded Pentaho CE 7.1 so that I can modify some reports but when I try to test them I get the error: Failed to locate scripting engine for language 'ECMAScript'. The global scripting is written in ECMAScript that is why I need the ECMAScript Engine. If someone can help convert to this to groovy that would also help.

function init(dataRow){  
    var tenantUrl = dataRow.get("tenantUrl");
    var user = dataRow.get("username");
    var password = dataRow.get("password");
    dataFactory.getConnectionProvider().setProperty("user", user);
    dataFactory.getConnectionProvider().setProperty("password", password);
    dataFactory.getConnectionProvider().setUrl(tenantUrl);
 }
