Deploying to Heroku

Questions & Help Questions

I’ve followed all of the documentation I can find regarding deploying to Heroku but am failing with a Mix.Config.LoadError

Relevant output from git push heroku master

remote: -----> Fetching app dependencies with mix
remote: ** (Mix.Config.LoadError) could not load config config/prod.secret.exs
remote:     ** (File.Error) could not read file

remote:  !     Push rejected, failed to compile Elixir app.

remote:  !     Push failed

So, it appears to be failing when it fails to find prod.secret.exs, however, as per the docs this file is no longer in use, doesn’t get imported anywhere and doesn’t exist in the repo any longer.

Not sure why I’m having this issue, any help would be greatly appreciated.

Thanks

check for and remove this line
import_config "prod.secret.exs"

in config/prod.exs

That line no longer exists. It was taken out before the first deployment attempt following the instructions in Deploying on Heroku — Phoenix v1.8.8

This is why I’m so confused.

hmm, can’t really see how it’s anything else.. confusing

can you double check - also that you have done a git commit so the git push heroku master is pushing the latest..

Indeed. I’m a few commits ahead.

I’m going to start afresh in the morning. It’s been a long day.

Thanks for the assistance.

Did you try it again? Any updates?
