Error with ESP8266 Compiling on Arduino IoT Cloud

[onostec]

Could you please check out this error I got while compiling on Arduino Iot Cloud

/usr/local/bin/arduino-cli compile --fqbn esp8266:esp8266:generic --build-cache-path /tmp --output-dir /tmp/2572720623/build --build-path /tmp/arduino-build-A8648914555524E4D21267121210C4A7  /tmp/2572720623/Untitled_aug28b

Huh, In whatever core you are using, it looks like they changed the serial configuration (like SERIAL_8N1) to be of type SerialConfig rather than an integer type.

What core/board are you using?

In the Arduino IoT cloud, I only selected the generic ESP8266 and attempted compiling.
