I have a docker container runnning a django application that is also running a cron job inside it. The managed command keeps failing due to this error:

SyntaxError: invalid syntax
My cron job looks like this:

The invalid syntax is from Python 2. You are using a version of Django that requires Python 3. Change your cron command so that it uses Python 3. If you use a virtual environment, then use the Python from the virtual environment.

This is a typical error you get when using a wrong Python version. Following your comment under the question:
The docker container is using python 3.5. When I run python -V, I get
Python 3.5.6
You can see that your user's $PATH points to Python 3.5.6 when using the shell session you open. There is one thing about cron jobs that often leaves people stuck with problems: cron opens a different shell and doesn't have access to your $PATH. So in your case it points to Python 2.x.
There are many ways to overcome this. Probably the easiest one is to check where your Python 3 is located by running
$ which python3
and using the path from the output in your cron command. For example, for my system it would be:
0 1 * * 1-5 /usr/bin/python3 manage.py myCommand
