# `Trellis.BackfillFailure`
[🔗](https://github.com/salesforce-misc/trellis/blob/v0.1.0-alpha/clients/elixir/lib/trellis/status.ex#L307)

A build that keeps failing: how many attempts have failed, the latest
error, and when it is tried again. It retries on its own, except that a
build failing for a reason no row explains pauses the transform after a
few attempts (`next_attempt_at` is then when it paused). Fix the cause,
resume a paused transform, and the next attempt goes through.

# `t`

```elixir
@type t() :: %Trellis.BackfillFailure{
  attempts: non_neg_integer(),
  last_error: String.t(),
  next_attempt_at: DateTime.t(),
  source_table: String.t()
}
```
