I have tested it also in versions 14,15 and 16 with no luck. I ended up deleting the file before every execution of puppeteer.launch(options).įor this to work on headless mode I set the parameter headless: 'chrome' and not true. I had to set both because when chromium first starts, it populates the user dir with its own files.Įvery time the browser restarts, the file SingletonLock that sits on the 'user-data-dir' foder has to be overwritten. user-data-dir=newly_created_folder -profile-directory=Profile 2 Then on puppeteer I launched chromium with the following flags: I pasted the previously created profile folder named 'Profile 2' inside the newly created folder. I created a new folder somewhere for chromium to use as its data directory. I set the downloads directory and the default behavior for PDFs to 'download PDFs'.

I got to a solution that does the job for now using a chrome profile. I tried launching chromium with the -print-to-pdf flag found in this list, with no luck.ĭoes anyone know, if puppeteer can launch chromium with the 'download PDF' as the default behavior, without tying it to a profile?ĭoes anyone know if there is another solution for puppeteer to download embedded pdfs? Plus, I can't test this solution on headless mode. The only solution I have come up so far is manually changing the default behavior in chrome://settings/content/pdfDocuments to download the PDF, but every time I restart the browser, it resets.

The link opens a new tab and its content look like this: Įmbedded is the pdf I would like to download.

I am visiting a page which has a link for a pdf file.
