Hi @hpmousse, I'm having the same issue, did you resolve it?

Old post, but having the same issue now. Did anyone find a definitive cause and fix? For me, it works fine on localhost but fails when run via Heroku where it has been running without issue for 4+ years. No code or stack updates, it just stopped working.

Have been having the same issue for over a week now. Runs fine on localhost (Mac terminal) but gives the 111 error when run on the production app (on Heroku) that has been running without issue for 4+ years. Zero code or stack changes on the production app. Really frustrating.

Same here, fine on localhost, 111 error on production app (running on Heroku). Zero code or stack changes in production. Error occurring for over a week now and cannot find a fix.
