Hi there,

I recorded my character in Character animator and tried impport to After effects, but It won't show in composition so I go back to Character Animator to export as video but all the layers I recorded were there but can't see anything on the scene and when I try to export this error message keep coming up:

Internal error code: (1682591070:3156+27) attempt to index a nil value
