semtree does not appear to recognise interaction terms in lavaan

[cicadawing]

Hi there!

Love the package
Works well for me, except when I specify an interaction term while writing my model in lavaan
E.g.
lav_obj <- 'y ~ x +z + x:z'
run_lav_obj <- sem(model = lav_obj , data = Data)

Above terminates fine. But when I run:
tree <- semtree(model=run_lav_obj , data=Data,
verbose = T, predictors=c('c'))

I get an error where it looks as though it is searching for the column x:z - which is created in the lavaan object.

Thanks for reporting this. I confirm that this is a bug in the current version.
