Dear @ixxxl,
Please, try wrapping the code inside ready event for the lookup field:

fd.field('Linia').ready().then(function(field) {
    field.disabled = true;
});

@Nikita_Kurguzov
Thank you, now it works, without errors

Yes, please, use ready event for complex fields, such as Lookup/Person/Attachments - they take time to load, and this ensures their availability.
