You need to set environment variable e.g export COMMUNES_FIX_PATH_JSON=$(pwd)/communes-fix.json with file communes-fix.json (content visible below). Athough the city dissapears in the official cities list, in the locaux, a reference to this particular city code is used. Without the addition, the info to get the name from the code made the code fails as seen in below thrown error.
