Marlin 2.1.1 error: #error "SERIAL_PORT must be from 1 to 6."

[2007-i]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

I downloaded Marlin 2.1.1 and I'm trying to assemble the firmware for the ISS ROBIN e3d board, but I constantly get an error during assembly
Marlin\src\HAL\STM32../../inc/../HAL/./STM32/HAL.h:62:4: error: #error "SERIAL_PORT must be from 1 to 6."

Serial ports set the same as always
#define SERIAL_PORT -1
#define SERIAL_PORT_2 1
