From 735b806d5d738ee05509c413fee22dfeb5dfbe7c Mon Sep 17 00:00:00 2001 From: Sheogorath Date: Mon, 9 Apr 2018 22:27:17 +0200 Subject: Add check for noteId length As we know the length of an UUID we can check if the base64 string of the provided UUID is long enough for a legacy base64 encoded nodeId and stop processing it in legacy mode, if it's not the case. This should make the ugly warning way less common.
