Warning for solving example ODE from docu

The following example code from the docu produces a warning. How can i get rid of it?

import jax.numpy as jnp
from diffrax import diffeqsolve, ODETerm, SaveAt, Tsit5


def vector_field(t, y, args):
    prey, predator = y
    α, β, γ, δ = args
    d_prey = α * prey - β * prey * predator
    d_predator = -γ * predator + δ * prey * predator
    d_y = d_prey, d_predator
    return d_y


term = ODETerm(vector_field)
solver = Tsit5()
t0 = 0
t1 = 140
dt0 = 0.1
y0 = (10.0, 10.0)
args = (0.1, 0.02, 0.4, 0.02)
saveat = SaveAt(ts=jnp.linspace(t0, t1, 1000))
sol = diffeqsolve(term, solver, t0, t1, dt0, y0, args=args, saveat=saveat)

Warning:

'jax._src.interpreters.partial_eval.DynamicJaxprTracer'>. Attempting to hash a tracer will lead to an error in a future JAX release.
warnings.warn(

Start by running the ODE example included in the issue and capture the warning with the project’s current dependencies. Trace the warning to the example or the affected solver path, then verify that the documented example runs without this warning and add or update a regression check if the repository has one.
