I'm actually not sure which of my migrations triggered this, but the whole lot of them are at: https://github.com/pmarreck/mpnetwork/tree/yolo/priv/repo/migrations

It was possibly 20190930174006_create_sessions.exs or any migration subsequent to that, based on the previous warnings

I fixed it by creating more a generic version of generating message that is now able to handle any danger type. I tested it on all your migrations and it works fine.

The fix is available in version 0.1.2 that I've just released on Hex. Thanks!
