    Please Help me understand what is going on because I get the following error every time when run from node.

    Best I can think is it has something to do with the \’ in volStr but I don’t know how to create it any other way.

    after @Mulvya comment I changed my for loop to

    var volStr = '';
    
for (var i = 0; i &lt; arrPairs.length; i++) {
    
    volStr += "volume=enable='between(t," + arrPairs[i].start + "," + arrPairs[i].end + ")':volume=0";
    
    if (i !== arrPairs.length - 1) {
    
        volStr += ",";
    
    }
    
}

    getting rid of the space between each grouping and it worked beautifully.
