Error reading tooltips

[Doriano-Ponzo-EOS]

I want to use table "Page Table Field" to read tooltips.

Add action with following code to a page (any):
action(TEST)
{
Caption = 'TEST';
Image = Start;

            trigger OnAction()
            var
                PageTableField: Record "Page Table Field";
            begin
                PageTableField.Reset();
                PageTableField.SetRange("Page ID", 456); //same with 8052
                if PageTableField.FindSet() then
                    repeat
                        Message(PageTableField.Tooltip);
                    until PageTableField.Next() = 0;
            end;
        }

Client crash reading table.

Does anyone know a way to read this information via AL from saas?
