Local fix

Problem summary

• When there is no pathinfo in the request, the code path results
  in no library being placed in the list of path elements. When
  the code attempts to retrieve the library from the array of path
  elements, the above exception is thrown, resulting in a 500
  response being sent to the browser.
  

Problem conclusion

• Check for an empty path list in order to pass the correct
  library name to the next method called.
