# requestBodyStreamExhausted

A body stream is needed but the client did not provide one.

## Declaration

```swift
static var requestBodyStreamExhausted: URLError.Code { get }
```

## Discussion

Discussion This impacts clients on iOS that send a POST request using a body stream but do not implement the URLSessionTaskDelegate method urlSession(_:task:needNewBodyStream:).
