Error when launching Dolos from Dodona for one particular exercise

[pdawyndt]

I was testing the new project naming when launching Dolos from Dodona. No issues with the first exercise I tried to analyse, but Dodona fails when trying to launch Dolos for this exercise.

Visually, the launch of Dolos keeps spinning. This is the error message I get in Chrome DevTools:

I consistently happens with this exercise, and consistently does not happen with the first exercise I tried to analyse.
