Hardware

WiFimanager Branch/Release: Master

Esp8266/Esp32:

Hardware: ESP-32 nodeMCU

Core Version: 2.4.0, staging

Description

I'm trying to update the firmware with OTA library function, I call the config portal with the BOOT button, but when I'm trying to upload the sketch, I get the next message in the serial monitor, I tried with all partitions scheme, with the same result:
.Bad Size Given

Settings in IDE

Module: NodeMcu

Additional libraries:
