Describe the bug

When starting the docker container with a read-only volume, the following error occurs:

I guess this is because the server tries to create the files and xml directories.

To reproduce

Mount volume read-only (or use any other read-only filesystem)

-v ./aasx:/AasxServerBlazor/aasxs:ro
