## Feature(s) impacted Rails deployment to production env in docker containers ## Observed behavior Build fails while trying to precompile assets in assets ## Expected behavior Build should succeed… ## Failure Logs ## Context Just installed forest to complete onboarding production and it fails when precompiling assets. Everything deploys fine when I remove forest again. The underlying culprit is the active storage module trying to access DO Spaces via s3 sdk. Not sure why adding forest to the gem file is making this fail, but it does make it undeployable at the moment. Anyone had a similar issue with rails? - Project name: LeanBOD - Team name: BOD Company - Environment name: Production - Agent type & version: Forest Liana 7.8 ---

Sure. here’s the stack trace that gets dumped. There’s nothing forest specfic in there I don’t think, but the fact that it’s hitting this in the first place is what’s wrong. That’s the config for ActiveStorage via DigitalOcean being triggered, which doesn’t happen if I remove forest from the Gemfile. Is there an initializer in the gem that is tripping this up? ```javascript Aws::Errors::MissingRegionError: No region was provided.

It seems that the issue comes from the absence of `AWS_REGION` env variable. Do you have this env variable in production ?
