FSWebServerLib.cpp:363:51: warning: 'const char* ArduinoJson::JsonVariantBase<TImpl>::asString()

[sekt1953]

Hej I am trying to use you FSBrowserNG.ino i am using Arduino IDE 1.8.1 with ESP8266 version 2.3.0
and selected NodeMCU 1.0 board but yhise errors when compiling

and more of the same.

do you have an idea what to change

This is caused by a change on AsyncWebServer library. I've updated my code to fix this on develop branch. Check #8
I've just updated master branch to implement this change

You fix is working on Arduino IDE 1.8.1 and 1.8.2 but I get a warning

Argghh I think I've made another duplicate -> #12 .

@sekt1953 can you try change these lines below on FSWebServerLib.cpp file:

    _httpAuth.wwwUsername = json["user"].asString();
    _httpAuth.wwwPassword = json["pass"].asString();

to this

    _httpAuth.wwwUsername = json["user"].as<char*>();
    _httpAuth.wwwPassword = json["pass"].as<char*>();

and see if it fixed your issues.

Also please style your comment, no offense but it's hard to read... 😄 Fence the code with triple back ticks.

Solved, I hope! thanx
