I am running self hosted prefect with work-pool type as docker. in my worker logs, the run crashes with error:

here is my Dockerfile:

RUN mkdir -p /opt/prefect/projectname
COPY . /opt/prefect/projectname/
WORKDIR /opt/prefect/projectname/
RUN pip install -r dt/pdf_reader/requirements.txt

here is the success deploy log:
