Formative component in a SEM

[Kev]

Hi everyone, my question is related to how to incorporate a formative component in the SEM model. 

So the CALF component is a canonical/formative component with no indicators. According to our hypothesis, it includes four latent variables (yellow circles), with their own indicators. 

However, when I try to run this model, the error message pops up. 

Any suggestions?

Thank you all so much. 

Best,

Kev
