How to combine pdf when one pdf file is stored on s3 bucket using combine pdf gem

In my task table I can access pdf file @task&.assignable&.pdf_file that is stored on s3 bucket. I can access to its url using @task&.assignable&.pdf_file.file.url

I want to add a new page in the same pdf file so I am using combine_pdf gem. It is getting path of file1 that I have generated with wicked_pdf but on line

pdf << CombinePDF.load(@task&.assignable&.pdf_file.file.url)

It is showing error:

No such file or directory @ rb_sysopen - https://patientiq1.s3-us-east-2.amazonaws.com/uploads/ < hashed_path >.pdf? < access_key >

file1_path = Rails.root.join('tmp', filename)
pdf = WickedPdf.new.pdf_from_string(
  render_to_string('patient_engagements/signed_page', layout: 'pdf', locals: { :@signed_pdf => @signed_pdf })
)
File.open(file1_path, 'wb') do |file|
  file << pdf
end

pdf = CombinePDF.new
pdf << CombinePDF.load(file1_path) # one way to combine, very fast.
pdf << CombinePDF.load(@task&.assignable&.pdf_file.file.url)
pdf.save "combined.pdf"

You can not use load with remote files, use parse instead

require 'combine_pdf'
require 'net/http'

url = "https://example.com/my.pdf"
pdf = CombinePDF.parse Net::HTTP.get_response(URI.parse(url)).body
