T-Rex errors on specific zoon level

[dmitrykinakh]

We are using https://github.com/t-rex-tileserver/t-rex/releases/tag/v0.14.1 version to do tiling. However, we have noticed that on some zoom levels. For this particular layer, it happens only on zoom level 11 (I've tried to generate up to z16)

docker-compose run --name TL_01 --rm trex-master sh -c 't_rex generate --tileset municipal_zoning_code --overwrite true --minzoom 10 --maxzoom 12 --extent -81.658619,28.346742,-80.863155,28.786278 --config /storage/trex/config.toml;'

Not sure that the problem is somewhere in data since in that case, that should be a problem on all zoom levels and not on a specific one. Looking for any recommendation on what to check in configs to prevent this.
