esp32 wifi websocket fastled -- crash

Postby raysconcept » Wed May 12, 2021 5:33 pm

///////////////////////////////////////////////////////////////////////////////////////////////

ISSUE: (code main.cpp is below)

I am working with ESP32, Wifi + WebSockets + ArduinoJson + Fastled and experiences crashes also.
It seems to run fine until I implement FastLed. I am sending instructions from nodejs (what leds to turn on etc) via websocket in json-format. It crashes when fastled.show(); is invoked;

just before the error occurs and crashes, the jsonparser stops working (results in null on all values)
then this error pops, and the esp is nonresonsive, the error message is even not completed
