Regression in AsyncWebServerResponse beginResponse

What happened?

This worked fine before merge (I've used me-no-dev's code) ->

  photoFrameBuffer = esp_camera_fb_get();
  photoFrameLength = photoFrameBuffer->len;
  photoFrame += String( (char *) photoFrameBuffer->buf, photoFrameLength );
  AsyncWebServerResponse *response = request->beginResponse( 200, "image/jpeg", photoFrame );
  request->send( response );

Now on the web client side I only get "<FF><D8><FF><E0>" ..

Stack Trace

PACKAGES:

• framework-arduinoespressif32 @ 3.2.0
• framework-arduinoespressif32-libs @ 5.4.0+sha.2f7dcd862a

Dependency Graph
|-- ESPAsyncWebServer @ 3.7.4
|-- ArduinoJson @ 7.1.0
|-- AsyncTCP @ 3.3.8

Minimal Reproductible Example (MRE)

  photoFrameBuffer = esp_camera_fb_get();
  photoFrameLength = photoFrameBuffer->len;
  photoFrame += String( (char *) photoFrameBuffer->buf, photoFrameLength );
  AsyncWebServerResponse *response = request->beginResponse( 200, "image/jpeg", photoFrame );
  request->send( response );

I confirm that:

• I have read the documentation.
• I have searched for similar discussions.
• I have searched for similar issues.
• I have looked at the examples.
• I have upgraded to the lasted version of ESPAsyncWebServer (and AsyncTCP for ESP32).
