I am new to docker and while running docker-compose build command i am getting this error.

The code in your container uses a newer version of python-dotenv than the one that is listed in the requirements.txt file, as the interpolate option was added in v0.11.0.

You will need to change the version in requirements.txt to 0.11.0 (or the most recent one) and reinstall the dependencies.

It seems your container uses a virtual environment. You may need to check that the dependencies are correctly updated in the container, either by running pip install in the Dockerfile, or by running it locally beforehand.
