So you're not running the docker image? Do note that Bedrock Dedicated Server is Mojang/Microsoft's software -- my image just automates the download and setup.

They only provide x86 binaries so you can't run on aarch64/ARM without an emulator. If you were using the docker image it would take care of that.

but if you use docker image

want to set
server.properties where is it in the path if checked using pwd
