There is a hotfix that need to be applied after the scheduled deployment. These are files not included on the current application revision so you uploaded them manually to the target instances. On the next application release, the hotfix files were included on the new revision but your deployment fails so CodeDeploy auto rollbacks to the previous version. However, you have noticed that the hotfix files that you’ve manually added were missing, and the application is not working properly.

Which of the following is the possible cause and how will you prevent it from happening in the future?
