ESP-Mesh arduinoJson lib error

[denkee]

Hello to all!
I wrote codes for esp32 boards, which will communicate via esp-mesh, but I have one problem... Boards are correctly connected via esp-mesh, but i got error on deserialization json.
Serial monitor tell me that's invalid input.

I apologize in advance in maybe not correct English, but my mother tongue is Slovak and I don't know English very well, so if I did something wrong, here's the reason.

Sender code (this esp32 is reading states of four switches and sending to two esp8266 boards which have two relays each):
