Невозможно получить доступ к веб-приложению Flask, развернутому в Azure: контейнер завершает работу с ошибкой

У меня возникли проблемы с веб-приложением Python Flask при его развертывании в Azure. Я следовал документации и настроил Dockerfile, но столкнулся с проблемами при попытке доступа к развернутому приложению. Ниже приведены соответствующие детали:

Докерфайл:

# Use the Azure Web App Python base image
FROM python:3.10

# Set the working directory in the container
WORKDIR /app

# Install FFmpeg
RUN apt-get update && apt-get install -y ffmpeg

# Upgrade pip to the latest version
RUN pip install --no-cache-dir --upgrade pip

# Copy the requirements file and install dependencies
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# Copy the Flask app code into the container
COPY . .

# Expose the port your Flask app runs on (usually 5000)
EXPOSE 5000

# Define the command to run your Flask app
CMD ["python", "application.py"]

Соответствующая часть application.py:

if __name__ == "__main__":
    application.run(host = "0.0.0.0", debug=True)

При доступе к домену своего веб-приложения Azure я получаю следующее сообщение об ошибке:

Ошибка при входе в домен:

:( Application Error
If you are the application administrator, you can access the diagnostic resources.

Как сделать приложение Flask доступным из Интернета при его развертывании в Azure? Буду очень признателен за любую информацию об ошибках в моих журналах.

Кроме того, обратите внимание, что мой образ Docker помещается в реестр контейнеров Azure (ACR).
