When I try to update a "Contacts" record on Dynamics 365 by using

the CDS - Update a record

I get the follwing error:

<!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 recreated the flow a few times. List record and get record work fine.

Is there a workaround? or does anyone have clue on how to get this running.

Regards,

Jan
