Symfony 6 | Consume streamed file and send it back to the client - php

Question

I am developing an administrator website.
There is a section that, when a button is pressed, sends a request to my Symfony backend and the Symfony backend makes an HTTP request to another API that responds with a raw Excel file.
The flow Im trying to make is:
Admin panel [http request] -> Symfony Backend [http request] -> Another API [Generate file and streams it back]
Another API [Streamed Excel file] -> Symfony Backend [Consume the stream] -> Admin panel [Save in device]
I tried doing it like this:
ReportsService
public function reserves_report(String $date1, String $date2): FileForwardResponse {
// This calls to the API to get the streamed file
$guestTypesHttpResponse = $this->httpClient->request(
'GET',
$this->get_endpoint('reports') . "/" . $date1 . "/" . $date2
);
// This class is just to organize things
return new FileForwardResponse(
$guestTypesHttpResponse->getHeaders(),
$guestTypesHttpResponse->getContent(),
);
}
Controller
public function reserves_report(): Response
{
$this->sessionService->singUserIn();
$fileResponse = $this->reportsService->reserves_report($date1, $date2);
return new Response(
$fileResponse->content,
200,
$fileResponse->headers,
);
}
What I was expecting to do is to recive the entire streamed file from the API to the Symfony backend and then use the headers from the API to make it available to download from the client since the headers looks like this:
+headers: array:12 [▶
"connection" => array:1 [▶
0 => "Keep-Alive"
]
"keep-alive" => array:1 [▶
0 => "timeout=5, max=100"
]
"x-ratelimit-limit" => array:1 [▶
0 => "600"
]
"x-ratelimit-remaining" => array:1 [▶
0 => "596"
]
"content-type" => array:1 [▶
0 => "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet; charset=UTF-8"
]
"content-disposition" => array:1 [▶
0 => "attachment; filename="filename.xlsx""
]
"expires" => array:1 [▶
0 => "Mon, 26 Jul 1997 05:00:00 GMT"
]
"last-modified" => array:1 [▶
0 => "Sat, 11 Feb 2023 15:51:36"
]
"cache-control" => array:1 [▶
0 => "cache, must-revalidate"
]
"pragma" => array:1 [▶
0 => "public"
]
"transfer-encoding" => array:1 [▶
0 => "chunked"
]
"date" => array:1 [▶
0 => "Sat, 11 Feb 2023 21:51:36 GMT"
]
]
And the response content looks like this:
What I got when I hit my Symfony endpoint is a 0 bytes file named filename.
If I hit the APIs endpoint from the browser directly it downloads it just right but I would like to know if there is any way to do it through Symfony http request.
