Same error also happens running in docker

[qtang]

Workaround is to upgrade Chrome (google-chrome-stable). Here's how I did it in docker:

$ docker exec -it safeway-coupons bash
root@safeway-coupons:/# apt update && apt upgrade -y

BEFORE:

root@safeway-coupons:/# safeway-coupons -c accounts_file -d -n

Since the dockerfile doesn't pin package versions, presumably the docker image just needs to be rebuilt and the apt command will pull the later version of the package...

Edit: This will rebuild you a new working docker container and tag it:
docker build -t localsafeway:latest https://github.com/smkent/safeway-coupons.git#main

Then you can run the freshly built localsafeway:latest image you just created.

Edit2: for future reference for those not as familiar with docker, to cleanup once the main package is updated and you want to delete the local version you just built you can run this to remove and untag the image you created:
docker rmi localsafeway:latest
and cleanup any other unused images:
docker image prune

[jvasa]

Thanks guys for the local fix, it does work and I updated to use the localsafeway image.

[JerboaGobi]

Not working for me. Current driver version:
ChromeDriver 123.0.6312.86

[jvasa]

Try in your docker-compose.yaml to change the line:
from: image: ghcr.io/smkent/safeway-coupons:latest
to:build: https://github.com/smkent/safeway-coupons.git#main
This way it will build the latest version when you start the docker, although it may take some time.

[JerboaGobi]

Should have been more verbose. I've been cloning the repo, main branch, and building and running it from the locally built version.

I do get some build errors when I do the process as you've described but I don't think that matters so much since cloning the repo and building it is effectively the same thing, unless I'm mistaken.

[tuxthepenguin84]

For those of you using Docker Compose and using the hosted image you can temporarily add the following to get the image updated before /entrypoint runs

entrypoint: ["bash", "-c", "apt update && apt upgrade -y && /entrypoint"]

[JerboaGobi]

I also the method suggested by @tuxthepenguin84

As far as I can tell the chrome debugger doesn't open the listening port.

`netstat -lnp

[JerboaGobi]

I had multiple issues. One of which was PID limits causing the process to not be able to spawn. The recommended solution to build the project locally and deploy that image did end up resolve the base issue.

[adrianbn]

Rebuilding like @jvasa mentioned #116 (comment) fixed the issue.

[borgified]

following @jvasa suggestion in #116 (comment) also fixed it for me (it should also fix #115). originally i was using v0.2.12 and getting this error when i exec'd into the container to run it manually:

root@f1f45bae1ff4:/# safeway-coupons
Clipping coupons for Safeway account XXXX
sendmail: bad address ''
Error: Authentication Failure (cannot access local variable 'driver' where it is not associated with a value)

when you build from scratch instead of using the prebuilt container, you get a new version of ChromeDriver. since this seems to be a recurring issue, would it make sense to factor out the ChromeDriver install and make it so that it can be upgraded without touching the rest of the safeway-coupon's code? Would it be possible to make a container that keeps ChromeDriver up to date, saving it into a volume that can also be mounted/shared into safeway-coupons container? That way we wouldn't have to rebuild everything from scratch every time.

apparently there's some auto updaters like these: https://stackoverflow.com/questions/66018451/how-to-get-the-chromedriver-automatically-updated-through-python-selenium-after

but i dont know if these will fit our use case. let me know if i'm on the right track, the next time this breaks, i'll try to automate it.

I have a wrapper script to use msmtp instead, and a config file for msmtp and of course the updates needed for the container upon start.
