CFA error

[Rev Uy]

Can someone help me in fixing this error? Thanks

There are lots of places where this can go wrong that are likely to be difficult to figure out without a reprex. Recommend removing all of the warning suppression and tests first. My hunch is that something didn't converge and was given a NULL or NA value that creates a type conflict. See here https://groups.google.com/g/lavaan/c/DCqxYiHq9OM

Hm. Not sure. Would you be able to send me a reprex? I will then
investigate. Please send it to Yves dot Rosseel at UGent dot be

Yves.
