Please let us know the command which is throwing this error upon execution.
i created a function, when I m trying to call it with my data at that time.
figarchfit = function(spec, data, out.sample = 0, solver = "solnp", solver.control = list(),
fit.control = list(stationarity = 1, fixed.se = 0, scale = 0, rec.init = 'all',trunclag = 1000),
numderiv.control = list(grad.eps=1e-4, grad.d=0.0001, grad.zero.tol=sqrt(.Machine$double.eps/7e-7),
hess.eps=1e-4, hess.d=0.1, hess.zero.tol=sqrt(.Machine$double.eps/7e-7), r=4, v=2))
