PiHole + unbound + macvlan realized with portainer

[Linksamwald]

Describe the bug
raspi5 with OS Bookworm
The container is created with portainer, starts successfully and is listed as "running".
But then this (Error description):

File 1.22.0/data/unbound.sh
Lines 394 to 401 are not executed.

The Container log shows:
exec /unbound.sh: exec format error

Expected behavior
A clear and concise description of what you expected to happen.

Error messages
The container starts and is listed as "running". In the container log, however, the following is repeated continuously (in a continuous loop):
exec /unbound.sh: exec format error

Additional context
The directories "dev" and "var" are not created. The group and user "_unbound" are not created, unfortunately I have no idea whether they are created. The last line with the execution command gives the error message that "unbound" is a directory and therefore cannot be executed. So do not get to the end of the line where the "unbound.conf" is located.

exec /opt/unbound/sbin/unbound -d -c /opt/unbound/etc/unbound/unbound.conf

Thank you for your attention!
