Recherchez l’opération snapToRoads dans les schémas YAML et JSON et inspectez son URL encodée. Corrigez la casse du chemin, de /v1/snaptoroads à /v1/snapToRoads, dans les fichiers de schéma concernés, puis vérifiez que les deux schémas contiennent le chemin corrigé et que l’URL en minuscules n’est plus présente.
