AMR no longer loads in new version of mira

[djinnome]

In mira 0.7.0:

git clone https://github.com/gyorilab/mira.git
cd mira
git checkout 0.7.0
pip install -e .
python
>>> from  mira.sources.amr import model_from_url
>>> url = 'https://raw.githubusercontent.com/DARPA-ASKEM/Model-Representations/pde-petri-amrs/petrinet/examples/pde/advection/advection_backward_1_0.01_3.json'
>>> model = model_from_url(url)
>>> model

results in:

TemplateModel(templates=[NaturalDegradation(rate_law=0.01*t, name='r_a_0_0_boundary', display_name=None, type='NaturalDegradation', subject=Concept(name='a_0', display_name='a_0', description=None, identifiers={}, context={}, units=None), provenance=[]), NaturalConversion(rate_law=-a_0*u/dx, name='r_a_0_1_0', display_name=None, type='NaturalConversion', subject=Concept(name='a_1', display_name='a_1', description=None, identifiers={}, context={}, units=None), outcome=Concept(name='a_0', display_name='a_0', description=None, identifiers={}, context={}, units=None), provenance=[]), NaturalConversion(rate_law=-a_1*u/dx, name='r_a_0_2_1', display_name=None, type='NaturalConversion', subject=Concept(name='a_2', display_name='a_2', description=None, identifiers={}, context={}, units=None), outcome=Concept(name='a_1', display_name='a_1', description=None, identifiers={}, context={}, units=None), provenance=[]), NaturalProduction(rate_law=-a_2*u/dx, name='r_a_0_boundary_2', display_name=None, type='NaturalProduction', outcome=Concept(name='a_2', display_name='a_2', description=None, identifiers={}, context={}, units=None), provenance=[])], parameters={'u': Parameter(name='u', display_name=None, description=None, identifiers={}, context={}, units=None, value=1.0, distribution=Distribution(type='StandardUniform1', parameters={'minimum': 0.0, 'maximum': 1.0})), 'dx': Parameter(name='dx', display_name=None, description=None, identifiers={}, context={}, units=None, value=1.0, distribution=Distribution(type='StandardUniform1', parameters={'minimum': 0.0, 'maximum': 1.0}))}, initials={'a_0': Initial(concept=Concept(name='a_0', display_name='a_0', description=None, identifiers={}, context={}, units=None), expression=0.4), 'a_1': Initial(concept=Concept(name='a_1', display_name='a_1', description=None, identifiers={}, context={}, units=None), expression=1.0), 'a_2': Initial(concept=Concept(name='a_2', display_name='a_2', description=None, identifiers={}, context={}, units=None), expression=0.4)}, observables={}, annotations=Annotations(name='Advection Model', description='Advection as Petrinet model created by Dan Bryce and Drisana Iverson (Mosaphir)', license=None, authors=[], references=[], time_scale=None, time_start=None, time_end=None, locations=[], pathogens=[], diseases=[], hosts=[], model_types=[]), time=Time(name='t', units=Unit(expression=day)))

However, when I run the same command in the most recent version of mira (with pydantic2)

git checkout main
pip install -e .
python
>>> from  mira.sources.amr import model_from_url
>>> url = 'https://raw.githubusercontent.com/DARPA-ASKEM/Model-Representations/pde-petri-amrs/petrinet/examples/pde/advection/advection_backward_1_0.01_3.json'
>>> model = model_from_url(url)

I get the following error:
