Migrating nRF53 Zigbee project to nRF54 results in ZBOSS errors

Question

Hi, 
 I try to migrate a working nRF53 Zigbee project from SDK 2.7 to the latest SDK and an nRF54. As described here, I also switched to Zigbee R23. The project structure is shown below. 
 
 But the build exit with the error message
