Adding a note to an existing timeslot results doesn't work

Using the feature/api-docs branch for !21 (merged) after applying the migration and creating a show and a schedule using the REST API, adding a note to an existing timeslot raises a TypeError exception:

django             |   File "/steering/program/views.py", line 688, in create
django             |     data={"show": show_pk, "timeslot": timeslot_pk} | request.data,

Can you specify which Python version was used? This syntax is available since Python 3.9. Do we have to target python <3.9?

I'm using the docker image and docker-compose and the image uses Python 3.8.

I'll update the Python version in the Docker image.
