This should work, or at least it shouldn't generate that error. But it
isn't the best way to get a template (or any object) if you already know
the id. It is better to do this:

  conn = ovirtsdk4.Connection(...)
  sys_serv = conn.system_service()
  tpls_serv = sys_serv.templates_service()
  tpl_serv =
tpls_serv.tmeplate_service('fedff75f-635f-4790-9bbf-2ac389e14f93')
  tpl = tpl_serv.get()
