Accept Reject sampler not working for multivariate pdfs

[Qazalbash]

For this piece of code,

from jaxampler.sampler import AcceptRejectSampler
from jaxtro.models import Wysocki2019MassModel
from matplotlib import pyplot as plt

model = Wysocki2019MassModel(alpha=0.8, k=0, mmin=5.0, mmax=40.0, Mmax=80.0, name="Wysocki2019MassModel")
sampler = AcceptRejectSampler()

samples = sampler.sample(target_rv=model, proposal_rv=model, scale=1.05, N=1000)

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.scatter(samples[:, 0], samples[:, 1], samples[:, 2])
plt.show()

we get this error,

jax.errors.SimplifiedTraceback: For simplicity, JAX has removed its internal frames from the traceback of the following exception. Set JAX_TRACEBACK_FILTERING=off to include these.

The above exception was the direct cause of the following exception:
