Starting with 0.93, FastAPI has updated the Starlette requirement which broke both titiler and titiler-pgstac (because Request.url_for now return a URL object, not a string), we fixed this upstream in titiler and titiler-pgstac.
ref: stac-utils/titiler-pgstac#80
Note: the FastAPI/Starlette requirements is set in multiple place in the project (pctiler, pcstac, pccommon) so extra care should be taking when changing it
