Document Intelligence Batch API format of jsonl file for azureBlobFileListSource file list

Question

The docs for the batch api preview https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/concept-batch-analysis?view=doc-intel-4.0.0 say that when using azureBlobFileListSource the fileList field should point to a jsonl file with the list of documents to process.

Unofrtunately, I cannot find anywhere what the format is for the lines in that file. I tried to put just the filename + path as a quoted string, but then I get

{"code":"InvalidContentSourceFormat","message":"Invalid content source: Could not parse JSON on line 1 in file list 'XXXX.jsonl'."}}}

Below is the syntax for azureBlobFileListSource attribute:

POST /documentModels/{modelId}:analyzeBatch
[
  {
    "azureBlobSource": {
      "containerUrl": "{your-source-container-SAS-URL}",
      "prefix": "trainingDocs/"
    },
    "azureBlobFileListSource": {
      "containerUrl": "{your-source-container-SAS-URL}",
      "fileList": "myFileList.jsonl"
    },
    "resultContainerUrl": "{your-result-container-SAS-URL}",
    "resultPrefix": "trainingDocsResult/",
    "overwriteExisting": false
  }
]
