Problem description

Here is my code,
from titiler.mosaic.factory import MosaicTilerFactory
mosaic = MosaicTilerFactory(router_prefix="apptilemosaic")
app.include_router(mosaic.router,prefix='/apptilemosaic')
however, it threw

[this should explain why the current behavior is a problem and why the expected output is a better solution.]

I'm sorry @qtsun but I can't understand what's your issue here. Please provide more information about the titiler/cogeo-mosaic version and a way to reproduce your issue 🙏

I just used following way to call MosaicTilerFactory, was there any problem?

Here is my API version,
titiler==0.13.0,fastapi==0.100.1, and I use docker image osgeo/gdal:ubuntu-full-3.3.1 to build my development environment,but
Here is my Dockerfile,

FROM osgeo/gdal:ubuntu-full-3.3.1
COPY ./search /root/code
WORKDIR /root/code
RUN sed -i s@/archive.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list &&
apt-get clean && \
apt-get update -y && \
apt install python3-pip -y &&
apt install ttf-wqy-microhei -y &&
apt install ttf-wqy-zenhei -y &&
apt install xfonts-wqy -y &&
apt install locales -y &&
locale-gen zh_CN.UTF-8 &&
mkdir -p /home/project/data &&
mkdir -p /home/project/upload/ &&
mkdir -p /home/data/logs
COPY ./core/docker-entrypoint.sh /usr/local/bin/
RUN chmod +x /usr/local/bin/docker-entrypoint.sh
ENTRYPOINT ["docker-entrypoint.sh"]
ENV LANG C.UTF-8
EXPOSE 54133

I'm so confused.

are you trying to use a mosaicJSON file? it seems you are passing a tif URL...
