Hi all,

Created following a sample JSONL format,
Uploaded in the GCS bucket. gs://xxx/newsam.jsonl
we have created our own custom model using the curl command.

curl -X POST -H "Authorization: Bearer $(gcloud auth print-access-token)" -H "Content-Type: application/json; charset=utf-8" -d "@model-request.json"

The pipeline was successfully executed and deployed in the model registry.
Model name is : LLM

From the model registry, we have created the end point.
End point name :
sample1
Endpoint id: 59XXX079194845184

When we test the end point using the curl command, it throws "internal error encountered," error 500.
