Hi,
Can you tell me why am getting this error?

 function void build_phase(uvm_phase phase);
 env = ac_lpc_env::type_id::create("env", this);
    //test_seq = ac_lpc_tx_seq::type_id::create("test_seq",this);
    sequencer = ac_lpc_sequencer::type_id::create("test_seq",this);
    
    if(!uvm_config_db#(virtual ac_lpc_if)::get(this, "", "vif", vif)) begin
      `uvm_fatal("ac_lpc_test", "No virtual interface specified for this test  instance")
    end 
    uvm_config_db#(virtual ac_lpc_if)::set( this, "env", "vif", vif);
  endfunction

ERROR: uvm_test_top [ac_lpc_test] No virtual interface specified for this test instance.

Thanks,
