Q: Can't precompile assets from Froala Editor on Heroku I tried to deploy on Heroku a version of my RoR app with wysiwyg-rails gem.
When deploying, I have this error message.
remote: -----> Installing node-v12.16.2-linux-x64
remote: -----> Detecting rake tasks
remote: -----> Preparing app for Rails asset pipeline

I also run rake assets precompile on my local machine and it works fine.
Do you have any ideas about how to solve it ?

A: Finally, I found how to solve it.
Just updated sass-rails gem from v5 to v6.
