Extract covariance matrix nonlinear fit

Using a JSL script, I would like to extract the covariance matrix of a nonlinear model. I have a 4PL curve. But when I request: m["Logistic 4P"]["Parameter Estimates"]["Covariance of Estimates"]["Reference"][""];

It is said that it is an outlinebox and therefore can't be converted into a Data Table, nor a matrix.

However, while right clicking on it, I can convert it in both, so it must be possible using JSL.

Any ideas?
