Fd control ready lookup null

Hi,
I create a list item. When I open it, I use custom JS to work with some data stored in control Lookup.
Code:

fd.spRendered(function (vue) {

$(fd.control("vPodpis")).ready(function () {
console.log(fd.control("vPodpis").value);
});

});

Sometimes, it returns an array of objects - stored data are the people from the company, for example:
image
There are three people selected, so it works great, but...
Sometimes, it returns null, so it becomes unreliable.
image

I can set Timeout for this JS code, but I think that's not the right way.

If it is necessary, I can send the export of the Display Form.
Thank you for help.

Hello @Stepan,

Try using the Plumsail API for the control, not jQuery:

fd.control('Control1').ready(function(control) {
    // alert selected option as a text string
    alert(control.value.Title);
});

Hello @mnikitina ,
I tried that, but it does work the same way as my solution above. May I send you the configuration?
Thank you,
Steo

@Stepan,

What do you mean with 'it does work the same way as my solution above'? Yes, please export the form and attach it to the post.
