on version 2.0.2 ,the saveOption function does not take effect when used in loop.

[Zhantongoscar]

the function: myWebServer.addOption(LONG_LABEL, longVar); could save data to fs and could be loaded later, but when i use saveOptions(); it work as follow code : // Config file will be opened on the first time we call this method .. myWebServer.saveOptionValue(LONG_LABEL, longVar); .. Serial.println(F("Application options saved.")); It seem not take effectect, is there somthing wrong in code:? my code is as follow:

void loop() {
  myWebServer.run();

  if (! digitalRead(BTN_SAVE)) {
// 
    loadOptions();
    Serial.printf("Application option loaded after web requestlongVar =%d\n",longVar);
    longVar++;
    Serial.printf("finished add n option loaded after web requestlongVar =%d\n",longVar);
// 
   saveOptions();
   Serial.printf("---------------------\n");
// 
    loadOptions();
    Serial.printf("Application option loaded after web requestlongVar =%d\n",longVar);
    longVar++;
    Serial.printf("finished add n option loaded after web requestlongVar =%d\n",longVar);

  //把longVar 保存的config文件中
  saveOptions();
     Serial.printf("========================\n");
    }
   delay(1000);
}

=========== Serial output： This are the current values stored:

LED pin value: 2 Bool value: true Long value: 1010 Float value: 15.500 String value: Test option String Dropdown selected value: Monday

Application option loaded after web requestlongVar =1010 finished add n option loaded after web requestlongVar =1011 Application options saved.

Hi @Zhantongoscar. Sorry for the late reply and thanks for reporting the bug. I'll get to work immediately to understand what could cause this malfunction

Hi again.

The error was in the customOptions.ino example. The method for saving options must be called with a true parameter in order to overwrite the config.json file

myWebServer.closeConfiguration(true);

thank cotestatnt for kindly answer! the esp_fs_weber lib is a great lib i have ever used in arduino. I follow it for years and use it as my base application in iot. thanks again!

by the way, we should update the code "myWebServer.closeConfiguration(true);" in save function at customOptions.ino example.
