Anytime i attempt to add a Oka label to Lake Country (Q1711455) i get the following error: "Unable to update entity: The supplied language code "oka" was not recognized." And than a second error which says "Unable to update entity: {}" pops up shortly after

Any suggestions for alternative solutions i can do instead?

sry i did not see you were gonna deprecate this feature

Am i the only one who finds it weird how a campaign like this can even be run without anyone on Commons having any awareness of it?
