Wicked_pdf: Error LibXrender1 on Heroku-18

[tomlober]

Hello,

Firstly thanks for your work ;)
The heroku-18 stack only includes libXrender at build time, not at runtime.

How to fix this ?

All the best,

According to this issue:

heroku buildpacks:add --index 1 https://github.com/heroku/heroku-buildpack-apt

Then add into project file Aptfile

libxrender1

Let me know if that works or not, otherwise, you can revert (for now) to an earlier Heroku stack with:

heroku stack:set heroku-16 -a example-app
git commit -m "upgrade to heroku-16" --allow-empty
git push heroku master
