# `Fil.UnknownError`
[🔗](https://github.com/pehbehbeh/fil/blob/v0.1.0/lib/fil/exceptions.ex#L166)

The storage reported something no other error describes. Log it and fail.

Adapters return it for storage responses nobody has mapped yet, with the storage's own term in `:reason`. Please
report it, so it can be mapped to one of the other errors.

# `t`

```elixir
@type t() :: %Fil.UnknownError{
  __exception__: term(),
  disk: Fil.Disk.t() | nil,
  op: Fil.Op.name() | nil,
  path: String.t() | nil,
  reason: term()
}
```
