How to get the list of groups along with the text of the pinned message?

Question

In contact with

I'm trying to do it through execute .
On 100 groups it seems normal, but 500 already falls off: "Runtime error occurred during code invocation: Too many operations".
groups.search has a limit of 1000. Apparently this error is due to map.push(event).
Are there any options for this to work on 1000 groups?

var events = API.groups.search({
    "q" : "*",
    "future" : 1,
    "type": "event",
    "offset" : 0,
    "count" : 10,
    "fields": "description,fixed_post"
});

var map = [];
if (events.count) {
    var i = events.items.length;

    do {
        var event = events.items[i];
        if (event.fixed_post) {
            event.fixed_text = "Текст из wall.getById";
        }
        map.push(event);
        i = i - 1;
    } while (i > 0)
}

return {
    "items": map,
};

There is a restriction on getting groups and information about users. You can't get more than 1000 users. You can't get more than 500 groups. Just use offset
