AttributeError: 'ecell4_base.core.NetworkModel' object has no attribute 'is_static'

I got the following error with this code.

%matplotlib inline
from ecell4.prelude import *

with reaction_rules():
    A + B == C | (0.01, 0.3)

run_simulation(10, {'A': 60, 'B': 60})

I'm using

ecell4                 1.2.0
ecell4-base            2.0.5

This was because I didn't update the version of echol4_base. Close this issue.
