```text
Failed to convert model to json: A fatal error occurred. The required library libhostfxr.so could not be found.
If this is a self-contained application, that library should exist in [/opt/openproject/vendor/xeokit-metadata/].
If this is a framework-dependent application, install the runtime in the global location [/usr/share/dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [/etc/dotnet].

The .NET runtime can be found at:
