Any clues why ./bin/test_generator.sh could fail in CI and run okay locally?

The failing test shows,

The template library behind the generator actually behaves differently on Mac and Linux (yes this is very stupid). I find the system to be the harshes on macOS, so the testing happens in macOS. Since what I have find is that if it works on macOS it also works in Linux but not the other way around. The issues is mostly around arrays. To not make it as simple as possible is there are several functions in the plugins file that transform arrays into strings. So what you are likely looking for in this case is: toStringArray.
