Downloading part of a file via /get_temporary_link with Range header returns incorrect content-type

thank u for letting us know

Thank you.  I also appreciate the acknowledgement on status.dropbox.com: https://status.dropbox.com/incidents/gp968mjw7t4d

Didn't see anyone else mention this yet so.

This happens even when not requesting part of a file; simply trying to access a `get_temporary_link` response directly returns the wrong content-type.

Broke the video viewing part of our mapping application.

rylincoln In my testing, this issue is not affecting requests not specifying "Range" to the temporary links returned by /2/files/get_temporary_link; I am not seeing the incorrect "Content-Type" in that case. Note that some media/video players do automatically set "Range" themselves though. If you are seeing otherwise however, please share a sample request/response so we can check on it.

@rylincoln That isn't something I can reproduce. Requesting the links returned by /get_temporary_link itself will just give me the correct Content-Type, a 200 HTTP response code and it will download without problems.

(edit) Ah, I see Greg already responded to this...

@De L.1 

I simply tested by generating a temporary link, copying that link directly into my browser URL and inspecting the request.

and i got back content-type: application/grpc

¯\_(ツ)_/¯

But i think Dropbox fixed the issue, cuz now i'm getting back correct content-type and our application plays videos as expected.

rylincoln Thanks for the note. I wasn't able to reproduce that exact behavior, but depending on how your device/browser was trying to play the video, it may have been automatically sending 'Range'. In any case, I'm glad to hear you're seeing it working again. We have begun to roll out a fix. Please note it will take some to fully deploy it.

Same for me (possibly with degraded performance) and I totally agree with you 🙂

It works for me sometimes, I presume that it's still rolling out.

i still get errors

The fix is rolling out and is not out fully everywhere yet.

now i get no errors anymore

thanks!

Thank you! It's working great now.
