Graphics stopped working about heroku-buildpack-tex HOT 5 CLOSED

@codingjoe thanks so much for the help! It's extremely useful to have this container for testing. The \includegraphics worked on it, so I guess on heroku it must be an issue with the image file or it's path or something along those lines, so we can probably close the issue.

@sschloesser I don't know if it might be helpful for your case but we had also an issue where some graphics stopped working with \includegraphics. In our case it was because the graphics were some generated thumbnails and somehow TeX Live 2017 had a problem with that. Our fix was installing TeX Live 2016 because there it worked. You can tell the buildpack the path it should use for the installer. just how it is documented here: https://github.com/Thermondo/heroku-buildpack-tex#custom-tex-live-version

Maybe that helps your case as well. Btw, if it does help, please make sure you are referencing the buildpack in heroku with the version number because we might soon introduce a breaking change where the file path is changed. Just as a heads up.

@sschloesser it always uses the latest version by default. But you can freeze the repo to a certain version, as @anneFly suggested.

Hi @sschloesser I know debugging these can be hard. I did setup a little docker based test suite right here: #18

I would recommend adapting it to your needs and building it locally to debug your issues.
Here is how you can do that:

1. Checkout the tests branch.
2. Add your texlive.profile or texlive.packages file to the repo root.
3. Run docker build . -t heroku-tex
4. Run docker run -ti -v PATH/TO/TEST/TEX/FILE/DIR /app/examples heroku-tex

That will put you inside a heroku container with your exact packages installed. Can can than run your TeX commands and debug whatever is wrong.

I hope that helps you :)

Let me know if I can be of further assistance,

Thanks @anneFly for the heads up! It turned out the problem was that I was using quotes around the image path \includegraphics{"path/to/image.png"} and removing them fixed it. So this buildpack changed from using Tex Live 2016 to 2017? Maybe that's what broke it because it was working before.
