Textract and antiword not working in Docker image

I have attached my Dockerfile. The image is built but the textract is not working for doc format.

FROM ubuntu:18.04
RUN apt-get update -qq \
    && apt-get install -y --no-install-recommends \
    mupdf-tools -y \
    tesseract-ocr -y \
    ocrmypdf -y \
    swig -y \
    build-essential -y \
    libssl-dev -y \
    libffi-dev -y \ 
    python3-dev -y\
    libmpc-dev \
    libgmp-dev \
    libmpfr-dev \
    lib32ncurses5-dev -y \
    gcc -y \
    python3 \
    python3-setuptools \
    python3-pip \
    antiword -y \
    && apt-get clean \
    && apt-get autoremove

ADD . /home/App
WORKDIR /home/App
COPY requirements.txt ./
COPY . .
RUN pip3 install --upgrade pip 

RUN pip3 install -r requirements.txt

VOLUME ["/data"]
EXPOSE 8080
ENV PORT 8080 
CMD exec gunicorn --bind :$PORT main:app --workers 4 --threads 4 --timeout 60 

This is my python implementation for textract

   try:
        try:
            import textract
        except ImportError:
            return ' '
        text = textract.process(doc_path).decode('utf-8')
        return text
    except KeyError:
        return ' ' 

The implementation is perfectly working on google-colab but not in Docker image.
