Are you using publisher to distribute application possibly based on a certain field value? It seems that a certain field value you want to distribute the application by is missing. I.e, say you selected a field(say, Manager) value 'Peter' and set trigger to reduce the app. Now if that Peter gets missing after a new reload, the publisher doesn't get the value and throws the error.

What is there in your task? not only reload, perhaps a reduction and distribution as well, right? If so, reload run might not cause a problem but the reduction/distribution. Check what reduction/distribution is there. And I didn't really understand your
