Error seems to block enhancements configuration, please visit this article and check.
It probably with your module is not installed properly, try reinstalling it.
There is one similar error logged here (in below link), but for different thing. So it might give you some hint (if reinstalling don't work)
Otherwise you can raise this issue on git, here
I now got it to work by reinstalling the NuGet package through the Package Manager Console using the following command
Update-Package EPiServer.Labs.BlockEnhancements -reinstall
The changes I saw after this was not directly tied to the BlockEnhancements module which I though but to the files in modules/_protected/episerver-telemetry-ui
I get the following error in the browser console when trying to inline edit a block in a content area (a feature from the Episerver Labs Block Enhancements project).
However, this works fine in the Alloy project so there is something in my project that's causing the issue but I can't find anything and I don't really know where to look.
Has anyone else experienced and solved this issue?
My project is running Episerver CMS 11.20.1 and EPiServer.Labs.BlockEnhancements 0.9.5
