Bug Description
I have attempted to estimate a CFA model with three latent variables, all of which are measured with three or more indicators. Since the hypothesis of multivariate normality is not met and the measurement scales are ordinal, I have selected the WLSMV estimation method. The model is estimated correctly without errors, and all the requested results are obtained except for the reliability coefficients (Cronbach's alpha and omega coefficient). In this case, the following error message is displayed:
This analysis terminated unexpectedly.
Error in diag(scales) %*% truevar: non-conformable arguments

Expected Behaviour
The values for Cronbach's alpha and the omega coefficient should have been obtained, calculated specifically for ordered categorical variables.
