Hi! Can you please provide an example of the VT file you are using? It seems it might not be compressed but I have yet to find one that it isn't. Thanks!

Update: I compressed mbtiles cause error

ibesora commented 4 years ago

Sorry, can you be more specific about what happened? I hadn't had time to look at the issue and I want to make sure it's something I do control. Thanks!

I use tippecanoe with -pC options to create mbtiles from geojson. This will compress tiles and causes error

ibesora commented 4 years ago

tippecanoe -pC disables compression, not enables it. Will add a check so it doesn't crash when tiles are not compressed Thanks for the info!
