# debug.opaque() function

-   Flux 0.68.0+
-   View InfluxDB support

`debug.opaque()` works like `pass` in that it passes any incoming tables directly to the following transformation, save for its type signature does not indicate that the input type has any correlation with the output type.

##### Function type signature

```js
(<-tables: stream[A]) => stream[B] where A: Record, B: Record
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### tables

Stream to pass unmodified to next transformation.
