Why I got this error "independent variables are collinear with the panel variable id" when running the xtivreg?

When running the code "xtivreg y (x = z) i.year##i.id, fe vce(cluster id)", I got this error "independent variables are collinear with the panel variable id". How to address this issue?

Thanks!
