April tags and MT9V034 sensor not working?

April tags detection does work with the standatd H7 R2 (sensor MT9M114).
But when I change the sensor to the MT9V034 and run the demo april tag detection I get:

Traceback (most recent call last):
  File "<stdin>", line 13, in <module>
RuntimeError: The requested operation is not supported by the image sensor.
OpenMV v4.4.1-62-gdfa1d099-dirty; MicroPython v1.19-omv-r6; OPENMV4-STM32H743
Type "help()" for more information.

Is this a bug?

The sensor doesn’t support RGB565. You need to switch to grayscale.
