Images saved using ActiveStorage different in production and development environments

[Sega100500]

Images are different in production and development modes. In this issue the problem was described in detail.

There is an assumption that encryption occurs at some level and the encryption key does not match (maybe based on the secret_key_base). I'm trying to understand at what level this is happening.

Important note

When viewing images thumbnails ("server selection"), all thumbnails are displayed in any environment.

Issue was solved (""It's not a bug, it's a feature" of the Rails)

Perhaps someone will find the information useful, I hope so.
