Page Auto Complete

[JFn]

Anyone have an idea what could be the cause of a Page Reference-Page Auto Complete field to fail with a javascript error

JqueryCore.js?v=1550490665:2 Uncaught TypeError: Cannot read property 'length' of undefined
    at Function.map (JqueryCore.js?v=1550490665:2)
    at Object.success (InputfieldPageAutocomplete.min.js?v=112-1550487061:1)
    at l (JqueryCore.js?v=1550490665:2)
    at Object.fireWith [as resolveWith] (JqueryCore.js?v=1550490665:2)
    at T (JqueryCore.js?v=1550490665:2)
    at XMLHttpRequest.r (JqueryCore.js?v=1550490665:2)

Even when making a new auto complete field, default settings with a simple template selector, and new page with just that field in it.

Running PW 3.0.125 (and 126, same result). Tested it on another 3.0.126, and there everything works fine, so it's probably not related to the core jQuery.

 

Edit, never mind, the admin > pages > search was  disabled. Making the autocomplete search, well, not functioning.
