Hi,
I am trying to use multithreading via EnsembleThreads() within a EnsembleProblem and apply a DiscreteCallback to terminate! the individual simulations under a certain condition. Unfortunately my simulation results in the subsequent error message. I am using julia v1.2.0 and DifferentialEquations.jl v6.8.0. I would appreciate any help with reading the error message and figure out where warn has not been defined appropriately. Thank you.
