struct config_wifi_struct {
  char ssid[30];
  char pass[30];
  char DHCP[5];
  char ip[20];
  char gt[20];
  char mac[20];
  char dns[20];
};

bool read_config_wifi(String msg_json_wifi_config){
  StaticJsonDocument<300> doc;
      
  DeserializationError error = deserializeJson(doc, msg_json_wifi_config);

  if (error) {
    Serial.print(F("deserializeJson() failed: "));
    Serial.println(error.f_str());
    return false;
  }

  strcpy(doc["ssid"], str.ssid);
  strcpy(doc["pass"], str.pass);
  strcpy(doc["DHCP"], str.DHCP);
  strcpy(doc["gt"], str.gt);
  strcpy(doc["mac"], str.mac);
  strcpy(doc["dns"], str.dns);
  strcpy(doc["ip"], str.ip);
  
  Serial.println(str.ssid);
  Serial.println(str.pass);
  Serial.println(str.DHCP);
  Serial.println(str.gt);
  Serial.println(str.mac);
  Serial.println(str.dns);
  Serial.println(str.ip);
  
  return true;
}

If I do this I get this error
