Bug Description

When submitting a job with a file in InputSandbox, the file is never uploaded to the SandboxStore.
The JobWrapper reports Total size of input sandbox: 0.00 MiB (0 bytes) and the job fails because the executable file is not found on the worker node.

Steps to Reproduce

1. Submit a job with an InputSandbox using the diracx CLI
2. The job will fail and you need to look at the Pilot StdOut

Expected Behavior

The InputSandBox is uploaded and used for the job execution.

Actual Behavior

The job fail with this :
