combine_pdf not combining the pdfs

I think I am missing something simple. Using combine_pdf: I am attempting to combine two pdf files into one pdf, and then send that resulting pdf with send_data in my rails app.

Here is my code in a controller:

pdf = CombinePDF.new

# returns an array, each element is a string of an absolute path 
# to the file I want to upload
absolute_upload_paths = @obj.attachments.collect {|obj| obj.my_attachment.path}

absolute_upload_paths.each {|upload_path| pdf << CombinePDF.load(upload_path)}

send_data pdf, filename: “my_combined_pdf”, type: "application/pdf"

What results is that a damaged pdf file gets sent which cannot be opened:

Adobe Acrobat Reader could not open 'VR_Voc_Eval-51.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).

What am I missing? How can I use this gem to combine two existing pdf files into one pdf and then send it to the user?

It looks like the README for that library calls .to_pdf when sending the data. Hopefully calling #to_pdf on the pdf object like in the example will fix your issue. 

send_data pdf.to_pdf, filename: “my_combined_pdf”, type: "application/pdf"
