[Python] ModuleNotFoundError: No module named 'app.routes.sst' inside Docker container with...

I think i tried different solutions, i spent many hours before sending this post, but still I cannot cope by myslef. I am running docker container with Rag chatbot. You will also notice that I am not copying app folder from my localhost into image because I mount volumes to the application, db and documents. Could u help me to solve the issue ? Here is the Dockerfile:

# Use a lightweight Python base image with necessary dependencies
FROM python:3.10-slim

# Set environment variables
ENV DEBIAN_FRONTEND=noninteractive \
PYTHONUNBUFFERED=1 \
PYTHONPATH=/app

# Install necessary system dependencies
RUN apt-get update && apt-get install -y \
build-essential \
cmake \
libgl1-mesa-glx \
libglib2.0-0 \
libpoppler-cpp-dev \
tesseract-ocr \
portaudio19-dev \
git \
ffmpeg \
mpg321 \
&& rm -rf /var/lib/apt/lists/*

# Set the working directory in the container
WORKDIR /app

# Copy the requirements.txt into the container
COPY requirements.txt /app/

# Install Python dependencies
RUN pip install --no-cache-dir -r requirements.txt

# Expose API port (FastAPI will run on port 8000)
EXPOSE 8000

# Copy the application files into the container
#COPY . /app

# Start the bash shell and keep the container running
CMD ["bash", "-c", "while true; do sleep 1000; done"]


I am running this container with that command:

~/projekty/chatbot1$ docker run -p 8000:8000 --name chatbot -v /home/myuser/projekty/chatbot1/vector_db:/app/vector_db -v /home/myuser/projekty/chatbot1/documents:/app/documents -v /home/myuser/projekty/chatbot1/rag-chatbot:/app -e OPENAI_API_KEY=your-api-key-here rag-chatbot


Inside container when i run tree, i get:

/app
root@319388c4b543:/app# tree

I am running my application inside container with this command:

uvicorn app.main:app --reload --host 0.0.0.0 --port 8000


And I get
