A fresh Arduino SMT32H750 project fails to build

I created a fresh Arduino project for the WeAct stm32h750 board and its build fails. Any suggestions?

platformio.ini

[env:weact_mini_h750vbtx]
platform = ststm32
board = weact_mini_h750vbtx
framework = arduino

main.cpp:

#include <Arduino.h>

void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
}

build log:

 *  Executing task: platformio run

100% reproducable for me one the latest platform version. Something is wrong with the variant and pinmap files for this board, looking at it…

No actually PlatformIO “just” fails to put the correct board identification macro in the build (missing from the JSON file and not autogen’ed correctly).

Adding

build_flags = -DARDUINO_WeActMiniH750VBTX

makes it work.

A PR is for that is pending in

It works. Thanks @maxgerhardt !!!
