What is the current behavior?

I use the provided code of step 1 and step 2 and get the following error:
Error: "Actions may not have an undefined "type" property. Have you misspelled a constant?".

          const generatedAsyncFunction = promiseListener.createAsyncFunction(
            'START_ACTION_TYPE',
            'RESOLVE_ACTION_TYPE',
            'REJECT_ACTION_TYPE',
          );

          const values = {
            type: REQUEST_ITEMS,
            payload: { eventName, request },
          };

          generatedAsyncFunction.asyncFunction(values).then(
            resolvePayload => {
              console.log('foo: ', resolvePayload);
            },

            rejectPayload => {
              console.log('bar: ', rejectPayload);
            },
          );

          generatedAsyncFunction.unsubscribe();

What is the expected behavior?
