Steps to reproduce

Reproducing the failure is very straightforward. Here is what you need:

  1. A Windows 10 system running version 1703 of the operating system. Doesn’t seem to matter whether it is the Home or Professional version.
  2. A native UWP in Windows 10 that has a webview within it.
  3. Use JavaScript to define a PouchDB database within the webview.
  4. Setup a CouchDB database on a server that can be accessed by the webview within the native app.
  5. Use JavaScript within the webview to invoke replication between the local PouchDB database and the CouchDB database on the server. Direction of the replication does not matter. The replication will fail no matter the direction and it fails every time without exception.

If you run this same scenario on Windows 10 version 1607, it will work just fine. I am betting this means nobody anywhere can replicate between PouchDB and CouchDB from within any webview on Windows 10 version 1703. This will work from the Edge Browser on Windows 10. It WILL NOT run correctly from within a Windows 10 native UWP app inside of a WebView.

Here is a little more information:
The return message we get from the error when the replication fails is "getCheckpoint rejected with". Don’t have much more info than that, as it is difficult to get any info out of the WebView when running it inside our app on a real device.

There are no proxies.

For reproducing it, I have provided some HTML and JavaScript code, and CouchDB database access. I provided this directly to a Microsoft employee as I do not wish to share the code or database access here. I will inform him of the issue number once I submit this. If you look at the JavaScript and HTML you will see it is very simple. Run this web app inside a WebView, and you can let it try replicate to a test database we have on the web. It will most certainly fail.

We are running CouchDB 1.6.1
