When testing the pdf(generated from pdflatex) before submitting to a conference in RAS-Papercept, I encounter the error: "Error 1010 Could not open file". The answer in faq section of RAS-Papercept did not help.
I have many images as PDF to retain the resolution of plots/texts in the figure. All the PDF images were exported from draw.io/app.diagrams.net
The error goes away, if I use PNG files. However, I want to use PDF images. Any help would be greatly appreciated.

Solution(not sure if it is an optimal):
If you are very closer to a conference deadline, then use(based on) qpdf to post-process your final PDF. The post-processed file does not give the Error 1010.
$ qpdf my_file.pdf my_file_new.pdf
