Encounter Error: `dup': can't dup NilClass (TypeError) #85

Hi,

I am encountering the following error when generating the site:

It looks like that some static file path is nil. After add the following checking in the plugin, it works:

 33     if default_lang != current_lang
 34       static_files.delete_if do |static_file|
 35 
 36         if static_file.instance_variable_get(:@relative_path).nil?
 37           
 38           # Remove "/" from beginning of static file relative path
 39           static_file_r_path    = static_file.instance_variable_get(:@relative_path).dup
 40           static_file_r_path[0] = ''
 41           
 42           exclude_paths.any? do |exclude_path|
 43             Pathname.new(static_file_r_path).descend do |static_file_path|
 44               break(true) if (Pathname.new(exclude_path) <=> static_file_path) == 0
 45           end
 46         end
 47       end
 48     end

I am wondering why this happens only to my site.

I get the same message "can't dup NilClass (TypeError)". I am using Ruby 2.3.0, selenium, selenium (0.2.11) selenium-webdriver (3.3.0, 2.53.4), win 7 , 64 bit. Firefox 50. Geckodriver v0.16. The problem is only whwn I use firefox. Any Idea how to solve the problem?

@ranj123 see if you can get it work by modifying the plugin following the code snippet I pasted above?

Thank you

I can't see the code snippet you mention in your reply. Can you sen it?

Thank you

Where should the code be written? In which file?
