I was using the multi-line painless script in the request to calculate the distance. after click the play I got the error message

status: 400, details: JSON5: invalid character '\n

Desktop (please complete the following information):

OS: macOS
Server Opensearch 2.6
Version 15.0.1

Reproduce Steps

Just write a multi-line painless script or follow my sample below

GET INDEX/_search 
{
  "query": {
    "bool": {
      "should": [
        {
          "match_phrase": {
            "name": "xxx"
          }
        },
        {
          "multi_match": {
            "query": "xxx",
            "fields": [
              "yyy",
              "yyy_2gram",
              "yyy._3gram"  
            ]
          }
        }
      ]
    }
  },
  "size": 100,
  "script_fields": {
    "distance": {
      "script": {
        "lang": "painless",
        "source": """double distance(double lat1, double lon1, double lat2, double lon2){
            double R = 6371; // Earth radius in kilometers
            double dLat = Math.toRadians(lat2 - lat1);
            double dLon = Math.toRadians(lon2 - lon1);
            double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
                        Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
                        Math.sin(dLon/2) * Math.sin(dLon/2);
            double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));

            return R * c;
          }
          return distance(doc['location'].lat, doc['location'].lon, params.lat, params.lon);
        """,
        "params": {
          "lat": 11.0,
          "lon": 11.0
        }
      }
    }
  }
}

Expected behavior No Error of status: 400, details: JSON5: invalid character '\n'

Hi @semsphy , the fix has been released in version 0.4.7, due to the workload, the highlighting and syntax auto-completion will be in the future roadmap, pls download the latest version and try it out, feel free to raise another issues if you meet any unexpected behavior
