Transforming a collection of objects into proper JSON format for seamless transmission in an ajax request

I'm struggling to understand why I keep encountering the 'Unexpected end of JSON input' error when attempting to stringify an object array and passing it to an ajax call.

$(document).on("click", "#frmcomplist_cmdPrint", function(){
let complist = [];
let testlist = [];
let testnum = 0;

for(x = 1; x < rowCount; x++){
    thisuser = $('#username'+x).html();
    thiscomputer = $('#compname' +x).html();

    if(thisuser != '' || thiscomputer != ''){
        complist.push({
            user: thisuser,
            computer: thiscomputer
        });
    }
}

jQuery.ajax({
    type: "POST",
        url: 'reports//complist_print.php',
         dataType: 'json',
         data: {functionname: 'computer_list', JSONList: JSON.stringify(complist)},
         success: function (obj, textstatus){
            if (!(obj.error == '')){
               jAlert(obj.error, 0 + 48, 'error', false);
            } else {

            }    
        },
        error: function (xhr, status, error){
            //alert(xhr.responseText);
            jAlert(error, 0 + 16, "error", false);
         },
         complete: function (xhr, status) {
            // dumps error/result 
           console.log(xhr.responseText);            
        } 
});
});

After some investigation, I successfully solved the issue. It turns out that the code was functioning correctly with the ajax POST method, but it wasn't retrieving the necessary information, leading to a misleading error message.
