We really need a node in Unreal Editor to throw a custom blueprint runtime error with a clickable link to the location where the error occured!
The Print node with a breakpoint is not a solution because the breakpoints are only locally saved and do not persist if I for example zip the project ( and then use the unzipped project ) or share the project on GitHub!
At the moment I use this super dirty workaround with the variable ThrowError of the type Actor always (un)set to None ( null ref ):
