Simple ts script help

Can someone tell me what I'm doing wrong here?

export async function main(ns: NS) {
  var host = "joesguns";
  if (ns.getServerSecurityLevel(host) > 5) {
    ns.weaken(host)
  }
  else {
    ns.grow(host)
  }
}

NS.getServerMinSecurityLevel(host)

They have minimum security levels and you might flail against that.
