return model.analyzeUnexpectedFailures(...)

that way the top level Promise will also reject if the thing explodes.

You drop errors on the floor which is going to make this super hard to debug.
They'll just get swallowed. You need:

.catch(function(e) { 
  console.log(e);
});

+      },
+    });
+  </script>
