Unable to write unkeyed list with RESTCONF PUT request

Bug Medium Resolved Won't Do Šimon Ukuš Peter Suna pt Wed, 12 Jul 2023 10:38:46 +0000 Tue, 8 Aug 2023 14:13:58 +0000 Tue, 8 Aug 2023 14:13:05 +0000 7.0.0 0 2 <p>I have identified an issue in netconf. This problem can be replicated using the simple model provided in the attachment.</p> <p>The issue occurs when a PUT request is sent to data with an unkeyed list. For instance, attempting to send this request to the provided "test.yang" model results in the problem.</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
