Exception on forms with Reference Selector

[snwayferry]

I am using the ExitIntent widget on a form that has a Reference Selector that opens a Page and when clicking the selector to open the page the following exception occurs:

TypeError: Cannot read properties of undefined (reading 'listen')

In Chrome Developer Tools the code in mxui.js where the exception occurs is the e.listen line below:

        1636: (e,t,n)=>{
            Object.defineProperty(t, "__esModule", {
                value: !0
            }),
            t.openSelectPage = function({selectionMode: e, initialSelection: t, pageSettings: n, datasourceConfig: o, currentObjectId: a, constrainedBy: s, onSelectionChange: c}) {
                const l = (o.constraint || "").replace(/\[%CurrentObject%\]/g, a)
                  , u = (0,
                r.createPageSelectionTopic)();
                window.mx.data.getBacktrack(a, s, ((a,s)=>{
                    (0,
                    i.openPage)(n, {
                        abortOnClientValidations: !1,
                        abortOnServerValidations: !1,
                        currentForm: null,
                        formParams: {
                            initialSelection: t,
                            pageSelectionTopic: u,
                            listViewSelectionMode: e,
                            dataSourceMixin: {
                                extra: {
                                    constraint: s ? a + l : "[0=1]",
                                    offlineConstraints: o.offlineConstraints
                                }
                            }
                        }
                    }, {}).then((e=>{
                        e.listen("commit", (e=>{
                            const t = (0,
                            r.readTopic)(u);
                            (0,
                            r.removeTopic)(u),
                            void 0 !== t && c(t),
                            e()
                        }
                        ))
                    }
                    ), window.mx.onError)
                }
                ))
            }
            ;
            var i = n(4204)
              , r = n(245)
        }

I have tried debugging it but in the obfuscated JavaScript it's pretty tough to figure out what is happening but I presume the way that the page for the Reference Selector is opened by the widget handler is not passing the required object parameter.
