How to preserve line breaks in text content de-identified with Data Loss Prevention?

I am using an API call content.deidentify to de-identify text content. It is working as expected, but newline characters get stripped.

API call

curl -s \
  -H "Authorization: Bearer $(gcloud auth print-access-token)" \
  -H "Content-Type: application/json" \
  https://dlp.googleapis.com/v2/projects/$PROJECT_ID/content:deidentify \
  -d @text-request.json \
  > text-response.json

Input

Eleanor Rigby 
Pharmacist 
Liverpool Hospital 
[email protected]

Output

{
  "item": {
    "value": "Eleanor Rigby Pharmacist Liverpool Hospital [email-address]"
  },
  "overview": {
    ...
  }
}

Is there any option I can add to the request to preserve the line breaks?

I found setPrettyPrint in the Java client documentation. Can I use this option when calling the API directly?

Solution

The issue had nothing to do with DLP.

I was sending invalid JSON:

{
    "item": {
        "value": "Eleanor Rigby 
Pharmacist 
Liverpool Hospital 
[email protected]"
    },
    "deidentifyConfig": {
        ...
    }
}

Replacing the newline characters with \n solved the problem.
