ecto.migrate failed with FunctionClauseError

Ubuntu 18.04.3 LTS

I've just attempted to upgrade my very small instance that hasn't been upgraded in quite some time. ecto.migrate is failing with the message:

Are there any resources on recovering from this while preserving data or manually migrating?
