Mounting of Docker volume results in a "Scrapy – no active project"

I am writing up a scrapy python project that scraps data for a future ML project. I decided to containerize my project in Docker – below is my DockerFile:

FROM python:3.9.12-slim-buster

WORKDIR /app

RUN apt-get update && apt-get install -y git

RUN pip3 install --upgrade pip

COPY requirements.txt requirements.txt

RUN pip install -r requirements.txt

ADD . /app

I am able to run the following command and my scraper will run successfully:

docker run -it  ufc-stats-scraper scrapy crawl ufc_future_fights -o future.csv -t csv

output:

....
 'robotstxt/response_status_count/404': 1,
 'scheduler/dequeued': 53,
 'scheduler/dequeued/memory': 53,
 'scheduler/enqueued': 53,
 'scheduler/enqueued/memory': 53,
 'start_time': datetime.datetime(2022, 4, 20, 2, 4, 7, 365309)}
2022-04-20 02:04:08 [scrapy.core.engine] INFO: Spider closed (finished)

However, the scraped data is stored in the future.csv file, which is local to the container. I read online that I should use the -v command and mount the containers folder. Below is the command that I am trying to use:

 docker run -it -v ${PWD}:/app ufc-stats-scraper scrapy crawl ufc_future_fights -o future.csv -t csv

However, I am getting the error message below when running this command:

Scrapy 2.6.1 - no active project

Unknown command: crawl

Use "scrapy" to see available command

I’m fairly new to Docker but was wondering if anyone had any input on what I could be doing wrong here. Thanks!

Update:

I started a bash session on two versions of my docker image. One session was unmounted and the other was mounted. The app folder contained all of the repos files in the unmounted session. The weird thing is that the app folder is completely empty on the mounted session. This would explain why the error message reads "no active project". I am really confused why the mounted image is empty though.

I feel like I might be misunderstanding how the the Docker bind mount stuff works.
