Soon you try to #include <AsyncJson.h>, the compilation broke in platformio. It however compiles file in Arduino IDE though.

Your lib_deps looks incorrectly specified for ArduinoJson, it should not have the ~ character.

That's no the issue. This was just an artifact when I tried out each version (from 6 beta -> 5.13.4) one by one.

I use PIO successfully and have the following in my lib_deps:

lib_deps=
  SPI
  ArduinoJson@5.13.4
  AsyncTCP
  ESP Async WebServer
  ESP8266_SSD1306
  LiquidCrystal_PCF8574
  ESPmDNS
  Wire
  EEPROM
  Update

The ArduinoJson 6.x betas are not supported and even advised against usage by the author. If you specify it as I have done above it will pin you to that specific version, you may need to do a clean build (remove the .piolibdeps and .pioenvs folders).

Add the following to your platformio.ini:

lib_compat_mode=2
lib_ldf_mode=chain+

these will configure the library dependency finder to only consider libraries that are supported for your target (esp32, arduino) and the chain+ will have it delve into the libraries to find their dependencies. The default settings (chain, 0) for the LDF may cause issues with the wrong libraries to be picked in a few cases (WiFi lib from Arduino/AVR picked up instead of the ESP32 built-in as example).

You can also add FS to lib_deps but with the two lines above it shouldn't be necessary.

  1. Adding those lines alone didn't solve the problem for me. So I tried your other suggestion: Adding FS to lib - which complained about WiFi.h dependency - then SPI.h. Once I added them all, with below, it finally compiled.
lib_deps=
  ArduinoJson@5.13.4
  ESP Async WebServer
  FS
  WiFi
  SPI

However, once I #include <AsyncJson.h> it went back to the original error (first in this thread).

There is a missing class type declaration in AsyncJson.h for sure, you will need to make sure you are including ESPAsyncWebServer.h BEFORE AsynJson.h to solve this.

@atanisoft . That's the issue (I've enabled formatting which rearranged includes. At one point I thought about that as well, but overlooked it. Thank you 👍.

Many thanks, I've encountered this exact issue in Arduino IDE 1.8.9 and resolved it just by ordering my includes

#include <ESPAsyncWebServer.h>
#include <AsyncJson.h>
#include <ArduinoJson.h>
