How to display files in a grid with details?

Question

Hi, 
 I found a code that explain how to display files in a grid, but my problem is that I can't create new columns with more information, for example the Description of the file. Please, can you give an advice? 
 This is my currect code. Thanks a lot. 
 load(
local!data: {
{
id: 1,
folderId: 4768/* Folder ids*/

},
{
id: 2,
folderId: 4947/* Folder ids*/

}
},
a!gridLayout(
label: "Documentaci&#243;n",
labelPosition: "ABOVE",
headerCells: {
a!gridLayoutHeaderCell(
label: "Nombre documento"
)
},
columnConfigs: {},
rows: {
a!forEach(
items: local!data,
expression: a!gridRowLayout(
id: fv!index,
contents: a!richTextDisplayField(
value: a!forEach(
items: folder(
index(
fv!item,
"folderId",
{}
),
"documentChildren"
),/*Getting documents from folder*/
expression: {
a!richTextItem(
text: document(
fv!item,
"name"
),
link: a!documentDownloadLink(
document: fv!item
)
),
a!richTextItem(
text: char(10),
showWhen: not(
fv!isLast
)
)
}
)
)
)
)
},
selectionSaveInto: {},
validations: {},
shadeAlternateRows: true
)
)

It's because you are not passing gridRowLayout contents in an array

Hi, To remove this error, you have to wrap up the content of the gridRowLayout() into brackets ("{}"). Thank You.
