Binary Responses
To return binary responses, such as PDF downloads, from your Vapor application, your HTTP response should include the X-Vapor-Base64-Encode header:
return $response->withHeaders([
'X-Vapor-Base64-Encode' => 'True',
]);
Lambda Response Size
Lambda limits responses to 6MB. If you need to serve a larger file, consider returning a signed, temporary S3 URL that your user may use to download the file directly from S3.
