Upon following the epic tutorial https://eic.github.io/tutorial-jana2/03-end-user-plugin/index.html, I'm encountering the following error with nothing being produced as output in eicrecon.root file.

Exception: Unable to open event source "2022-09-26_ncdis10x100_minq2-1_100ev.edm4hep.root": No suitable generator found! Backtrace:

This is a problem with an outdated tutorial rather than an EICrecon issue. You can follow the instructions to locate and download a more recent file from here: https://eic.github.io/tutorial-analysis/setup.html or check whether any of the more recent tutorials meet your learning requirements more closely. It is worth creating an issue highlighting this problem on the tutorial github repository: https://github.com/eic/tutorial-jana2

Although eicrecon could probably exit more elegantly on this error
