Search endpoint returning 500 internal server error

This same API has been working solidly for years, but now in the past 2-ish days it has been returning more and more errors.

Sometimes it works for quite a while, but sometimes it keeps erroring for every single request.

This is happening to several dozen people at the moment, although all using the same app.

 

SDK doesn't seem to matter, as I'm seeing it on very old as well as the very latest versions (Objective-C/iOS).

 

Couldn't find anyone else reporting this and all the status pages and blogs aren't mentioning this either, so I'm assuming it's a new bug/issue.

 

More error context:

DropboxInternalServerError[{
    ErrorContent = nil;
    RequestId = 69738b83eefc634b2c5058b038aa0dd0;
    StatusCode = 500;
    UserMessage = nil;
}];
