Now that you have created your batch job, use the presigned_url to upload your .jsonl file directly to the designated storage location using the following command:
curl --request PUT \
--url '<YOUR_PRESIGNED_URL>' \
--header 'Content-Type: application/jsonl' \
--data-binary '@your_input_file.jsonl'
Replace <YOUR_PRESIGNED_URL> with the presigned_url and @your_input_file.jsonl with the path to your actual file.
