RivetBuild checks the OS version of the host system, and is using this as the storage path for the analysis.
The used container for the RunRivet and BuildRivet jobs is Alma9, while lxplus native is RedHatEnterprise9.
If one submits RunRivet from lxplus it looks for RivetBuild with RedHatEnterprise9 in the path, but the RivetBuild jobs only produce binaries for Alma9.
