Error 400. The size of the request headers is too long

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>

<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>

Thanks for reporting this issue. We are investigating it.

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.

Goodmorning,

 

I've got the same error for a specific view in Dynamics 365.

0x80072500 <!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>

 

I don't know how to fix this.
