GET request to /files/download fails with "The network connection was lost"
Hi,
Our app uses Dropbox's HTTP API to upload and download files. Since a few days ago, some of our app's requests are failing with "The network connection was lost". This issue was first reported on May 2nd. Our app uses React Native.
The failing request downloads files from Dropbox using a GET request to https://content.dropboxapi.com/2/files/download (code). A simplified version of the request looks like this:
fetch("https://content.dropboxapi.com/2/files/download", {"headers":{"Dropbox-API-Arg":"{\"path\":\"/info.json\"}","Authorization":"Bearer TOKEN_HERE","Content-Type":"application/octet-stream"},"method":"GET"})
If I use POST instead of GET, the request consistently returns the content of the file. However, as commented here, using a POST request with an empty body seems to fail in React Native/iOS. Dropbox doesn't seem to allow a non-empty body for this request.
Sometimes, the above fetch does work. However, I can reproduce the failure consistently by sending the above request twice, but only in some environments:
• Running code from the Safari development tools, inspecting a WebView in our application.
• Running code from the React Native Hermes development tools.
I can't reproduce this when using the same code in a NodeJS REPL or the Firefox JavaScript console.
