I've been using the following solution on Linux:
chromium-browser --headless --print-to-pdf=example.pdf 'https://example.com/'
(which is the same as this answer) and it was working fine, but now it says:
[0811/165809.082646:ERROR:headless_shell.cc(174)] Open multiple tabs is only supported when remote debugging is enabled.
I'm on Chromium version 83.0.4103.97-0ubuntu0.20.04.1
.
I'm not trying to open multiple tabs, and the web pages I'm trying to get PDFs from don't open popup windows or anything like that.
Is this just a bug or is there something else I should be doing?
