Hello! I am trying to create a new variable on a Data View using this painless script, but when trying to save, I am getting the generic error "Invalid Painless Script". The error also tells be to fix the highlighted errors, but there are no highlighted errors. Here is the script in question

```auto
if (doc.containsKey("ProcessCrash_split")){ 
    def processCrash = doc["ProcessCrash_split"].value; 
    int commaIndex = processCrash.lastIndexOf(","); 
    if (commaIndex > 0){ 
        emit(processCrash.substring(commaIndex+1));
        return;
    } 
    emit(processCrash);
    return;  
} 
emit("noCrash");
return;

```

Note: \* this script works on the dev tools query editor, replacing "emit(\*\*\*)" with "return \*\*\*"

Hello Mark,

The script you pasted here and the one in the image are different. Try using exactly what you pasted here.

```auto
if (doc.containsKey("ProcessCrash_split")){ 
    def processCrash = doc["ProcessCrash_split"].value; 
    int commaIndex = processCrash.lastIndexOf(","); 
    if (commaIndex > 0){ 
        emit(processCrash.substring(commaIndex+1));
        return;
    } 
    emit(processCrash);
    return;  
} 
emit("noCrash");
return;

```
