After upgrading from 3.1 to 4.0 I’m receiving this error when attempting to launch the job composer:

Exception: OodApp::SetupScriptFailed

'RAILS_ENV=production bin/rake db:setup' failed with output:

The error states ‘No such file or directory’, but I can see that the file does exist at that location:

[root@master ~]# ls -la /opt/ood/ondemand/root/usr/share/gems/3.3/ondemand/4.0.0-1/extensions/x86_64-linux/3.3.0/ffi-1.16.3/ffi_c.so

Any help getting past this error is appreciated. Thanks!

I’ve resolved the issue.

ldd /opt/ood/ondemand/root/usr/share/gems/3.3/ondemand/4.0.0-1/extensions/x86_64-linux/3.3.0/ffi-1.16.3/ffi_c.so

revealed that libffi.so.6 => not found. I’m running OOD on Rocky Linux 9, which had libffi 3.4 installed. Installing the package ‘libffi3.1’ installed the necessary library and ldd doesn’t report any ‘not found’ libraries.

The Job Composer is now loading without issue.
