mbtiles database is empty

[bartek977]

Hi, I have problem with some geojsons converted to mbtiles. After converting the mbtiles is empty - all tables have no records.

Geojson:

{"type":"FeatureCollection","features":[{"type":"Feature","id":"EigenTopografiePunt.fid--3fdcbd9f_189b6579d15_-1e7a","geometry":{"type":"Point","coordinates":[5.11939194,52.09288733]},"geometry_name":"geometry","properties":{"pkid":"nl.imkl-TS1383.BGI_brug-b","ucCode":"TS1383","status":"bestaand","clickable":0,"sourceId":"eigentopografie-punt-bestaand"}},{"type":"Feature","id":"EigenTopografiePunt.fid--3fdcbd9f_189b6579d15_-1e79","geometry":{"type":"Point","coordinates":[5.11939194,52.09288733]},"geometry_name":"geometry","properties":{"pkid":"nl.imkl-TS1396.BGI_brug-b","ucCode":"TS1396","status":"bestaand","clickable":0,"sourceId":"eigentopografie-punt-bestaand"}}],"totalFeatures":2,"numberMatched":2,"numberReturned":2,"timeStamp":"2023-08-07T11:28:49.128Z","crs":{"type":"name","properties":{"name":"urn:ogc:def:crs:EPSG::4326"}}}

command used to generate mbtiles: tippecanoe -zg -o file.mbtiles --drop-densest-as-needed file.geojson . I converted 43 files using these parameters and 4 mbtiles are empty. Any ideas on what should I do to generate vector tiles from these geojsons?
