Fork me on GitHub

Hi! I’m trying to run etaoin on heroku/linux but I get the dreaded “invalid argument: can’t kill an exited process” error. Firefox looks like it starts fine when I start it from the command line:

~ $ /app/vendor/firefox/firefox -headless
*** You are running in headless mode.
` To make things even trickier, I don’t get any logs from the driver when running
(e/firefox {:log-stdout "ffout.log" :log-stderr "fferr.log" :driver-log-level "trace"
                                   :path-driver  "/app/vendor//geckodriver"
                                   :path-browser "/app/vendor/firefox/firefox"})
Here’s my full error:
09:59:32.270 INFO  [] aah-crawler.enterprise - start

Any heroes on here who has any ideas how to fix this?


Or simply how to find/create the firefox log files?


Just a quick glance at your logs it seems you have the following path that may or maynot be the issue:
