Not working with Laravel Octane (Roadrunner)

[carestad]

I use this code in my controller to generate a excel file:

$excelWriter = SimpleExcelWriter::streamDownload('some-excel-file.xlsx');

foreach ($data as $row) {
    $excelWriter->addRow($this->formatRows($columns, $row));
}

$excelWriter->toBrowser();

When running locally with artisan serve everything is well, but in production or locally with Laravel Octane, I get the error RoadRunner can't communicate with the worker and I get a 500 error.

Locally, Roadrunner dumps some raw Excel data before processing the request stops.

Has anyone else experienced this and know of a potential solution?
