1) Click on Upload file on Filetype column
2) Select Pdf and press ok.
3) when file is uploaded check the post request header on Developer console and also S3 storage pdf file content type is set as "text/plain"

Note: If you get a browser JS error please run npm run dev. This will provide source maps and a much more useful stack trace.
@daaku Hi can anybody help me with this?
This issue should be fixed in the newest version of Parse Server (2.2.11)
@drew-gross
This issue still exists.
I have tested today by uploading pdf file and on amazon s3 metadata it shows text/plain.
Can you reopen the bug on the parse server repo and include the server logs?
I still have the problem in here when trying to upload a pdf file.
