I’m getting this error:
## ** (Ecto.Query.CompileError) Tuples can only be used in comparisons with literal tuples of the same size

from this line in an Ecto query:

dynamic([mi], where: mi.updated_at >= ^datetime or ^conditions)

mi.updated_at is defined as: timestamps(type: :utc_datetime)

The incoming published_after is a unix epoch value which I convert to a DateTime with from_unix()

Pretty new to dates in Elixir in general, so I’m not sure what is going on. Any help?

    conditions =
      if published_after do
        {:ok, datetime} = DateTime.from_unix(published_after, :second)
        Logger.info("published_after: #{published_after}")
        Logger.info("datetime: #{datetime}")
        ## log output:
        ## [info] published_after: 1546312169
        ## [info] datetime: 2019-01-01 03:09:29Z
        ## ** (Ecto.Query.CompileError) Tuples can only be used in comparisons with literal tuples of the same size

        dynamic([mi], where: mi.updated_at >= ^datetime or ^conditions)
        # updated_at defined as:- timestamps(type: :utc_datetime)

      else
        conditions
      end
