We use our custom script in .NET (with iframes, some javascript and Ajax requests) for preview campaing and from time to time we see in IS_Event_PreviewDataPop function empty values for IS_Attr metadata items. This is very strange and we don't know what is the cause. In this function for the empty values and make skip call, but this is only temporary solution, because it generates very much skip, raise attempts etc.
...
...
function IS_Event_PreviewDataPop(p_names, p_values) {
try {
if (IS_Attr_nr_gos.value == undefined || IS_Attr_nr_gos.value == "" || parseInt(IS_Attr_nr_gos.value) == 0) {
SkipCall("Empty");
return;
}
} catch (e) {
SkipCall("Empty");
return;
}
....
//make preview, attribute is good
}
...
How to resolve this problem? What me be the cause of this situation? Where can I find logs with errors?
Any suggestions?
