nRF Mesh example with provisioner board

Hey, I want to create a Bluetooth Mesh Network with the nRF52DK from Nordic. One board should be the provisioner and two more boards should be my nodes.

For my first test, I used the Zephyr examples "Mesh Provisioner" and "Mesh" on the nRF Connect 2.4.1 SDK and the 2.4.0 Connect Toolchain.

So I have flashed the "Mesh Provisioner" on one board and the "Mesh" example on two more boards.

I can add both nodes with the provisioner, and it seems that this part works too. (because when I added one node, I can't see his advertising anymore)

But when I click on the Botton1 of one of the Nodes, there should be a broadcast call and turn on the other LED, but I always get the Message "The Generic OnOff Client must be bound to a key before sending."

Normally, should the provisioner give the node this Key, so I'm not sure what I'm doing wrong.

This is the output of the Provisioner:
