# nil-error-return

**Default severity:** `error`

Reports explicit nil error results inside a branch entered because an error is
non-nil. Returning success there silently discards the failure.

## Bad

```go
if err != nil { return nil, nil }
```

## Good

```go
if err != nil { return nil, err }
```
