ModuleNotFoundError: No module named 'ufl'

Hi, I use docker to run this project,
docker pull ghcr.io/computationalphysiology/cbcbeat:v2023.2.0
docker run -it ghcr.io/computationalphysiology/cbcbeat:v2023.2.0

A error has arisen when I run demo_biventricular.py through Docker,

python3 ./demo_biventricular.py

The returned content is as follows:
Traceback (most recent call last):
File "/app/demo/bidomain-biventricular/./demo_biventricular.py", line 270, in
main()
File "/app/demo/bidomain-biventricular/./demo_biventricular.py", line 192, in main
application_parameters = setup_application_parameters()
File "/app/demo/bidomain-biventricular/./demo_biventricular.py", line 55, in setup_application_parameters

return message[0] % message[1:]
TypeError: unsupported operand type(s) for %: 'dolfin.cpp.parameter.Parameters' and 'tuple'

**So I deleted this line of code：**info(application_parameters, True)
**but another error arises,

The returned content is as follows:**

You need to change the import from

import ufl

to

import ufl_legacy as ufl

Note that I plan to move most of the functionality from cbcbeat to fenics-beat (https://github.com/finsberg/fenics-beat), including the bidomain solver, but bidomain is not my main priority at the moment.
