Content type application/octet-stream does not have a factory to be parsed

Describe the bug

Hi I am following this guide to export the docx file

https://learn.microsoft.com/en-us/graph/api/driveitem-get-content-format?view=graph-rest-1.0&tabs=php#query-parameters

Giving error "Content type application/octet-stream does not have a factory to be parsed"
` try {

        Log::info("oneDrivePath " . $oneDrivePath);
        // Get the source document ID
        $docxDriveItemId = $this->getDriveItemIdByPath($oneDrivePath);

        Log::info("Attempting to retrieve PDF content for DriveItem: " . $docxDriveItemId); // Log before the get


        $requestConfiguration = new ContentRequestBuilderGetRequestConfiguration();
        $queryParameters = ContentRequestBuilderGetRequestConfiguration::createQueryParameters();
        $queryParameters->format = "pdf";
        $requestConfiguration->queryParameters = $queryParameters;

         // Get the PDF content by appending format=pdf to the request
        $pdfContent = $this->graph->drives()
            ->byDriveId($this->drive_id)
            ->items()
            ->byDriveItemId($docxDriveItemId)  // Append format parameter directly to ID
            ->content()
            ->get($requestConfiguration)
            ->wait();

...
`

can you please help where I am going wrong

Expected behavior

It should give pdf content

How to reproduce

use the php library

public function exportDocxToPdf($oneDrivePath, $oneDrivePDFPath): array | Exception
{
    try {

        Log::info("oneDrivePath " . $oneDrivePath);
        // Get the source document ID
        $docxDriveItemId = $this->getDriveItemIdByPath($oneDrivePath);

        Log::info("Attempting to retrieve PDF content for DriveItem: " . $docxDriveItemId); // Log before the get


        $requestConfiguration = new ContentRequestBuilderGetRequestConfiguration();
        $queryParameters = ContentRequestBuilderGetRequestConfiguration::createQueryParameters();
        $queryParameters->format = "pdf";
        $requestConfiguration->queryParameters = $queryParameters;



         // Get the PDF content by appending format=pdf to the request
        $pdfContent = $this->graph->drives()
            ->byDriveId($this->drive_id)
            ->items()
            // ->byDriveItemId($docxDriveItemId . '?format=pdf')
            ->byDriveItemId($docxDriveItemId)  // Append format parameter directly to ID
            ->content()
            ->get($requestConfiguration)
            ->wait();



        Log::info("PDF content retrieved successfully.");

     } catch (\Exception $e) {

        Log::error('Error exporting DOCX to PDF: ' , $e->getTrace() );
        throw new Exception('Error exporting file to PDF: ' . $e->getMessage());
    }
}

### Configuration

_No response_

### Other information

_No response_

Start with the PHP SDK v2.24 request in the issue, especially ContentRequestBuilderGetRequestConfiguration and the drives/items/content method chain. Reproduce the format=pdf request and trace where application/octet-stream is parsed. Done means determining whether the SDK or request handling causes the error and documenting or correcting the path to retrieve PDF content.
