Conflicting Public File and Page File
One of your public files has the same path as a page file which is not supported. Since only one resource can reside at the URL both public files and page files must be unique.
Rename either the public file or page file that is causing the conflict.
Example conflict between public file and page file
public/ hello pages/ hello.js
Non-conflicting public file and page file
public/ hello.txt pages/ hello.js
