Fix IO error

```
- Rake assets install
  - Detected rake (`rake` gem found, `Rakefile` found at `/workspace/Rakefile`)
  - Running `bundle exec rake -P --trace` .... (1.6s)
  - Compiling assets with cache (detected `rake assets:precompile` and `rake assets:clean` via `bundle exec rake -P`)
  - Loading cache for /workspace/public/assets
  - Loading cache for /workspace/tmp/cache/assets
  - Running `bundle exec rake assets:precompile assets:clean --trace`

      ** Invoke assets:precompile (first_time)
