I'm not familiar with Julia and CUDA languages, so I'd like to ask for your help.
How can I set the initial values for a function in ExaModels as shown below?

function my_function(;data_at_t0 = 0, dt=0, backend = CUDABackend())

    m = ExaCore(backend = backend)
    
    xend, dx = 1, 0.1
    xrange = 0:Int.(xend/dx)
    
    C_next = variable(m, xrange, start = 1)
    C = variable(m, xrange, start = 1) # <- previous data 
    
    constraint(m, C[x] - data_at_t0[x] for x in xrange) 
    # constraint(m, f(C_next, C) for x in xrange) 
    return m
end
data_at_t0 = CuArray([0 for i in 0:11])

m = my_function(;data_at_t0 = data_at_t0, dt = 0.5)

Then, i got this error.
ArgumentError: invalid index: ExaModels.ParSource() of type ExaModels.ParSource

How can I input indexed information into the function with backend = CUDABackend?
