creating new concept error

when I click "save" button after I create a new concept, it does not work. the console in the web shows that react.js has some error. the following function : data clone error, the object can not be clone. how to fix it function F(e, t) { var n = t[Ro]; n === void 0 && (n = t[Ro] = new Set); var r = e + "__bubble"; n.has(r) || (ec(t, e, 2, !1), n.add(r)) } function Vu(e, t, n) { var r = 0; t && (r |= 4), ec(n, e, r, t) } var Fr = "_reactListening" + Math.random().toString(36).slice(2); function pr(e) { if (!e[Fr]) { e[Fr] = !0, of.forEach(function(n) { n !== "selectionchange" && (Xv.has(n) || Vu(n, !1, e), Vu(n, !0, e)) }); var t = e.nodeType === 9 ? e : e.ownerDocument; t === null || t[Fr] || (t[Fr] = !0, Vu("selectionchange", !1, t)) } }
