Hi, I tried your branch, it fixed the initial error but now I get this one:

Failed to prepare dynamic resources: NodePrepareResources failed for claim lab/mps-gpu-7c9db8954b-mbwj5-mps-gpus-682s2: error preparing devices for claim 37925188-b216-4aa3-8ca7-f32cf28476ae: prepare devices failed: error applying GPU config: MPS control daemon is not yet ready: error listing pods from deployment

@dekonnection I added permissions for job and pods. Hopefully that will fix the errors.
