How to get all groups from tabulator table - tabulator

Question

I need an array of "group" objects from a multi-level-grouped tabulator table where
group = { field: String, name: String }
but when I try to parse the payload of tabulator.getGroups(), I'm missing one of the groups. Is there a tabulator api function for retrieving all the groups from a table? tabulator.getGroups() was the only function I could find in the docs.

let data = [
{
"partType": "Disc Brake Pad",
"vehicle": "2019 chevy silverado",
"brand": "Cardone",
"partApplication": "Left Front/MKD794"
},
{
"partType": "Disc Brake Pad",
"vehicle": "2019 ford F150",
"brand": "STS",
"partApplication": "Left Front/MKD794"
},
{
"partType": "Disc Brake Rotor",
"vehicle": "2019 chevy silverado",
"brand": "Cardone",
"partApplication": "Left Front/MKD795"
},
{
"partType": "Disc Brake Pad",
"vehicle": "2019 chevy silverado",
"brand": "Cardone",
"partApplication": "Left Front/MKD795"
},
{
"partType": "Disc Brake Caliper",
"vehicle": "2019 chevy silverado",
"brand": "Cardone",
"partApplication": "Left Front/MKD796"
}
]
let columns = [{
title: "Part",
field: "partApplication"
}, ]
let table = new Tabulator('#tabulator', {
data: data,
columns: columns,
groupBy: ["vehicle", "partType", "brand"]
})
function groups() {
let groups = []
let groupComponents = table.getGroups()
if (groupComponents.length == 0) return groups
for (var i = 0; i < groupComponents.length; i++) {
groups.push({ field: groupComponents[i]._group.field, name: groupComponents[i]._group.key })
}
let groupList = groupComponents[0]._group.groupList
while (groupList.length != 0) {
for (var i = 0; i < groupList.length; i++) {
groups.push({ field: groupList[i].field, name: groupList[i].key })
}
groupList = groupList[0].groupList
}
return groups
}
Call groups() in the codepen console. { field: "brand", name: "STS" } is missing from the array, yet is displayed in the table. I tried to paste the result here but couldn't figure out how to copy the result from codepen.
Thanks in advance!

Check Console
https://codepen.io/dota2pro/pen/NmVzmv
const getAllGroups = function(input){
for(let i=0; i< input.length; i++){
console.log(allRows[i].getGroup());
// Use this or
console.log(allRows[i].getGroup()._group.key
,allRows[i].getGroup()._group.field);
// Use this
console.log('field: ', input[i]._row.modules.group.field,'key:',input[i]._row.modules.group.key );
}}
