I am embedding Lucid diagrams by just pasting the Lucid document url into confluence, however when I try to change the Viewer Type to Rich Viewer I get a error popup in the bottom left saying with the title "Lucid Chart Macro" and the text "Failed to update the diagram".
I've been able to do this previously, and a Lucid diagram I've added previously works fine with the Rich Mode.
...
While writing this question I've found a workaround solution, although I think this is still a bug that should be fixed as its confusing to the user as the error message gives no clue on how to resolve the issue.
Solution:
If you need to embed a Lucid diagram into confluence and want it to be updated (i.e. using the Rich Viewer mode), you cannot do this by just pasting the lucid url into the page body in confluence. Although this does easily allow you to embed a image, the Rich viewer mode won't work and you'll get an error if you try to turn it on.
Instead, use the insert item menu or type "/lucid" into the body and click the option. From here, select the diagram using the Lucid document explorer modal.
Adding the diagram this way will allow the Rich Viewer mode to be selected without error.
