I modified the page ./admin/src/containers/HomePage/Index.js following Strapi documentation https://strapi.io/documentation/developer-docs/latest/guides/custom-admin.html#introduction.

All works well locally, I also did a build locally, but I am not able to see this modified page after deploying to Heroku.

I tried to desactivate node_modules caching (like this: https://devcenter.heroku.com/articles/nodejs-support#cache-behavior), and I also pushed the file I modified on the repository via a custom .gitignore config like this to avoid cache troubles:

*.cache/*
!.cache/admin/
*.cache/admin/*
!.cache/admin/src
*.cache/admin/src/*
!.cache/admin/src/containers
*.cache/admin/src/containers/*
!.cache/admin/src/containers/HomePage
*.cache/admin/src/containers/HomePage/*
!.cache/admin/src/containers/HomePage/Index.js

This config only push the file Index.js but not the rest. But it also doesn't work.

I also installed this cache manager plugin (https://help.heroku.com/18PI5RSY/how-do-i-clear-the-build-cache) but the purge command and redeploying does'nt solve the problem...

Do you have any idea about how to see my modified admin on Heroku ?

Thank you !
