@monooso did you find a solution to this? I have the exact same issue :(

from cloak_ecto.

I'm having a similar issue when stopping and restarting my application. I suspect it's because I have my vault not being started early enough in the supervision tree. I'm going to try moving it up and see if that fixes it.

EDIT: That didn't seem to do it. Maybe there's some kind of Application.ensure_started call needed? Or maybe I'm barking up the wrong tree altogether.

i'm trying to migrate data like:

1. fetch record
2. decrypt content
3. DateTime.to_date()
4. encrypt
5. update

pretty simple usecase, but getting the same error. i understand Vault is a Genserver, but starting it manually doesn't help.

the guides/how_to/encrypt_existing_data.md page suggest to use IEX or a mix task for this so do i understand correctly that unless you're using a custom server (with elixir installed) you can't use this package in production? pretty major oversight, great package otherwise.

Solution (edit)

actually I just figured it out. you start the Vault with MyApp.Vault.start_link() and the ETS table error goes away.

real solution is to either support this officially or document it somewhere.

I've documented the workaround in #47.
