When saving a site as a template, an error such as the one below may be displayed. Viewing the ULS logs isn’t much help as it displays similar error information and also a NullReferenceException. I had a similar error with a custom list and deleting all of its items resolved the error. Since I was not saving data (Include Content checked), I knew that it wasn’t necessarily a data issue. The root cause ended up being view throttling. For some reason, the view throttles for a regular user were preventing large lists from being exported. This error can be worked around by temporarily increasing the web application’s list view throttles.
