Testing TiPg and we've having issue getting any of the tile endpoints to work. Some we can see specific errors like https://ogcapi.bgs.ac.uk/tipg/collections/public.aeromag_web/tiles/WorldMercatorWGS84Quad/2/1/2 results in `{"detail":"str contain unsafe (non word) characters: \"LINE_NUMB-SEG\""}` However most like http://ogcapi.bgs.ac.uk/tipg/collections/published.gb_625k_bedrock_fault_geology_dykes_wgs84/tiles/WebMercatorQuad/{z}/{x}/{y}.png result in: `│ INFO: 10.233.64.45:39070 - "GET /tipg/collections/published.gb_625k_bedrock_fault_geology_dykes_wgs84/tiles/WebMercatorQuad/8 ││ /137/179.png HTTP/1.1" 422 Unprocessable Entity ` The features endpoints appear to work fine. All suggestions welcome
