Hello Guys

Currently, I'm having issues connecting to a Sharepoint list. When I define the data source and set a field as visible I get the following error:

WebAuthoring abnormal termination.
Client date/time: 2016-12-13T04:06:07.822Z
Version: 2.0.562
Session ID: 0a64cf4c-5cfa-2282-922c-7274620a32af
errorMessage: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<HTML><HEAErD><TITLE>Bad Request</TITLE>
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<BODY><h2>Bad Request - Request Too Long</h2>
<hr><p>HTTP Error 400. The size of the request headers is too long.</p>
</BODY></HTML>

Sometimes I do get additional information like

callStack: Core.ApplicationError: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<HTML><HEAD><TITLE>Bad Request</TITLE>
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<BODY><h2>Bad Request - Request Too Long</h2>
<hr><p>HTTP Error 400. The size of the request headers is too long.</p>
</BODY></HTML>

Please help!

Am having the exact same issue. Is there any update on this reported issue?

This is currently a known issue and we are working to provide a fix for it soon.

For the time being, please use PowerApps studio (windows Client) instead of PowerApps web if you encounter this issue.

Thanks.
