API returns invalid PDF

[thomasjetzinger]

Hi!

I have an endpoint which should allow the user to fetch a PDF, which is returned as bytearray, from an internal reporting server. This PDF should then be returned to the client:

`const pdfAsByteArray = await reportService.generateReportAndWait(user.user, reportParameters);

return this.response.header('Content-Type', 'application/pdf').sendFile(pdfAsByteArray);`

I've also add the media type "appication/pdf" to the "Binary meda types" section in the API Settings of my REST api.
From my understanding the byte array should be converted to base64 and then automatically be converted back to binary in the client.

But the on client the response is still in base64 format!

What I'm doing wrong?
