Symfony version(s) affected

≥ 6.3.0

Description

When investigating #51360 I found out the HttpClientTrait::normalizeBody checks if upload streams have ended when they are nested in body (cf. #49911).

In that case, the HttpClientDataCollector will trigger an exception because it will call normalizeBody again when all streams have been read (to generate the cURL command).

How to reproduce

$stream = fopen('filepath', 'r');

$httpClient->request('POST', '/endpoint', [
    'body' => ['stream' => $stream],
]);

will trigger a TransportException if the profiler is enabled.

Possible Solution

The HttpClientDataCollector does not generate a cURL command when the body is a stream, so I guess it shouldn’t either in this case.
