Difficulty loading raster tiles from generated GPKG

[zacharyburnett]

I am creating new geopackages in Python from Numpy arrays, using Rasterio to create subdatasets.

I can open the geopackage in QGIS and view the rasters, but they do not show at all in Leaflet, although the console shows Draw tile messages as if the tiles are being rendered.

I am not all too familiar with geopackage creation, so perhaps it is my fault and I am not correctly initializing something.

If you can send me the GeoPackage you created I can take a look

I don't know what I changed, but now the console gives the following error, which is more helpful than before:

leaflet-geopackage.js:11910 Uncaught TypeError: Cannot read property 'adjustTileMatrixLengths' of undefined
    at new GeoPackageTileRetriever (leaflet-geopackage.js:11910)

Here is the geopackage I'm using. From reading online I think my problem is a malformed tile matrix, but I have not idea how to access that table to check.

This GeoPackage has a tile table with the 2d-gridded-coverage type. This extension is not support (currently) by GeoPackage-JS. I will fix the bug that is causing that table to show up in the list of tile tables.

On a side note, DB Browser For SQLite (https://sqlitebrowser.org/) works well for opening GeoPackages to check on things.

Thank you! I will attempt to get it into a tiled format.
