Newbie difficulty using mosaicjson

[cobra811]

I have successfully deployed TiTiler on AWS with the SAM one-click deploy. I have also successfully generated a single tile using the /cog endpoint: https://myendpoint.execute-api.us-east-1.amazonaws.com/cog/tiles/WebMercatorQuad/10/294/395.png?url=s3://sentinel-cogs/sentinel-s2-l2a-cogs/18/S/UH/2023/5/S2B_18SUH_20230510_0_L2A/TCI.tif. I ultimately wanted to use mosaicjson so that I could generate seamless xyz tiles on the fly with Maplibre. However, I have ran into a wall trying to generate a single virtual mosaic with sentinel 2 data. It seems that the /mosaicjson is expecting an existing virtual mosaic already? I thought TiTiler would create the mosaic, maybe I am wrong on this? I guess I'm not connecting the dots on how to create the virtual mosaic so that I can then use something like: https://myendpoint.execute-api.us-east-1.amazonaws.com/mosaicjson/tiles/WebMercatorQuad/10/294/395.png?url=<some url where the mosaic is?...>

You can create a mosaicjson file using https://github.com/developmentseed/cogeo-mosaic
