Dear Daniel,

Im trying to estimate a model using your R package since I want to use FIML.
When I´m trying to estimate my model I get the error: Error in h(simpleError(msg, call)): error in evaluating the argument 'x' in selecting a method for function 'rowSums': subscript out of bounds

I tried to run your example code to see what might be the problem and encountered the same problem when executing: sqrt(diag(vcov_complex(lavaan.fit, ids = ess.dk$intnum))).

The rest of the example code works fine.

I attached the session info with the loaded packages if necessary, although i checked if i have outdated packages (which i do not).

Do you know what could be the issue?
Best regards from Germany,
Matthias
