[BUG]: SID example crashes at Triton inference stage (24.03.01 runtime image)

[pdmack]

Version

24.03.01

Which installation method(s) does this occur on?

Docker, Kubernetes

Describe the bug.

A manual test and a variant of examples/nlp_si_detection/README.md reveals a core dump in a SID pipeline test. Confirmed against both Triton 23.10 and 24.03. In fact, the request is never properly formed by the tritonclient library.

The validation test succeeds ./scripts/validation/sid/val-sid-all.sh. However, that test uses CSV for the input file as opposed to jsonlines.
