I just notice I got this Logs in my docker container regarding the LiveTable Macro:

This is also my code on how I show the results and also adding the buttons to export the data:
{{velocity}}
#set($columnsProperties = {
'name' : { 'type' : 'text', 'size' : 30, 'sortable': true, "html" : "true" },
'language' : { 'type' : 'text', 'size' : 20, 'sortable': true, "html" : "true" },
'description' : { 'type' : 'text', 'size' : 100, 'sortable': true, "html" : "true" },
"doc.author" : { "type" : "text", "link" : "author"},
'_actions': {"sortable":false,"filterable":false,"html":true,"actions":["edit","delete", "select"]}
})
#set($currentUser = $xcontext.getUser())
#set($query = “where doc.author = ‘$currentUser’”)
#set($options = {
'className' : 'Culturati.DataTypes.ItemClass',
'queryParams' : {
'xpage' : 'livetable',
'class' : 'Culturati.DataTypes.ItemClass',
'query' : $query
},
"extraParams": "&doc.author=$currentUser"
})
#set($columns = [‘name’,“doc.author”, ‘language’, ‘description’, ‘_actions’])
#livetable(‘PreferencesTable’ $columns $columnsProperties $options)
{{livetableExporter livetable=“PreferencesTable” format=“csv” /}} {{livetableExporter livetable=“PreferencesTable” format=“excel” /}}
{{/velocity}}
I appreciate any help
Thanks in advance
