Nice job :) I left a comment on project, but you can do the same for study and scenario

Thank you for your feedback !

Almost perfect, can you just rename the functions checkFields => checkProjectFields, checkScenarioFields, checkStudyFields ? Otherwise we have 3 functions checkFields which are exported, it's not very practical

Of course it's done
