Cod Tracker API not working anymore

Hey
I was wondering why my Commands are printing out "unexpected identifier". The commands worked fine for about 2months. I didn't change everything now it prints out "unidentified identifier"
Maybe someone of you knows the problem.
Just a simple Command which worked fine but now gives me "unexpected identifier":

$(eval s=$(urlfetch json https://api.tracker.gg/api/v2/warzone/standard/profile/atvi/saehmon%231980116).data; n=s.platformInfo.platformUserIdentifier;`Stats von ${n}`)
