  • In the live site it is not loading some of the default email templates at the time of creating new template based on them, but it is working on my local site perfectly.

  • So, I have compared both the ajax responses I am getting, and came to know in the live site below script is added at the begining of the response, which cause this issue.

    Script which cause the issue:

==================================================

  • On the live server I am using New Relic for site performance monitoring.

  • When New Relic is enabled it adds this script code at the beginning of the email template ajax response, which cause invalid JSON syntax and because of this it stop further processing template and it will not load template content.

  • I have looked for the solution and one possible way is, if we disable New Relic then email templates will work fine and once we have done with our changes we can re-enable it back.

  • In the live site it is not loading some of the default email templates at the time of creating new template based on them, but it is working on my local site perfectly.

  • So, I have compared both the ajax responses I am getting, and came to know in the live site below script is added at the begining of the response, which cause this issue.

I have the same issue on one of the my project I am working on and figured out why this is happening, so I am posting it here, so it can be useful to others.

  • In the live site it is not loading some of the default email templates at the time of creating new template based on them, but it is working on my local site perfectly.

  • So, I have compared both the ajax responses I am getting, and came to know in the live site below script is added at the begining of the response, which cause this issue.

    Script which cause the issue:

    (window.NREUM || (NREUM = {})).loader_config = {xpid:"UgcCVVFTGwcDV1lXDwk="}; window.NREUM || (NREUM = {}), __nr_require = function(t, e, n) { function r(n) { if (!e[n]) { var o = e[n] = {exports: {}}; t[n][0].call(o.exports, function(e) { var o = t[n][1][e]; return r(o ? o : e) }, o, o.exports) } return e[n].exports } if ("function" == typeof __nr_require) return __nr_require; for (var o = 0; o < n.length; o++) r(n[o]); return r }({1:[function(t, e) { function n(t, e, n) { n || (n = {}); for (var r = o[t], a = r && r.length || 0, s = n[i] || (n[i] = {}), u = 0; a > u; u++) r[u].apply(s, e); return s } function r(t, e) { var n = o[t] || (o[t] = []); n.push(e) } var o = {}, i = "nr@context"; e.exports = {on: r, emit: n} }, {}], 2:[function(t) { function e(t, e, n, i, s) { return u ? u -= 1 : r("err", [s || new UncaughtException(t, e, n)]), "function" == typeof a ? a.apply(this, o(arguments)) : !1 } function UncaughtException(t, e, n) { this.message = t || "Uncaughterrorwithnoadditionalinformation", this.sourceURL = e, this.line = n } function n(t) { r("err", [t, (new Date).getTime()]) } var r = t("handle"), o = t(6), i = t(5), a = window.onerror, s = !1, u = 0; t("loader").features.push("err"), window.onerror = e, NREUM.noticeError = n; try { throw new Error } catch (d) { "stack"in d && (t(1), t(2), "addEventListener"in window && t(3), window.XMLHttpRequest && XMLHttpRequest.prototype && XMLHttpRequest.prototype.addEventListener && t(4), s = !0) } i.on("fn-start", function() { s && (u += 1) }), i.on("fn-err", function(t, e, r) { s && (this.thrown = !0, n(r)) }), i.on("fn-end", function() { s && !this.thrown && u > 0 && (u -= 1) }), i.on("internal-error", function(t) { r("ierr", [t, (new Date).getTime(), !0]) }) }, {1:5, 2:4, 3:3, 4:6, 5:1, 6:14, handle:"D5DuLP", loader:"G9z0Bl"}], 3:[function(t) { function e(t) { r.inPlace(t, ["addEventListener", "removeEventListener"], "-", n) } function n(t) { return t[1] } var r = t(1), o = (t(3), t(2)); if (e(window), "getPrototypeOf"in Object) { for (var i = document; i && !i.hasOwnProperty("addEventListener"); ) i = Object.getPrototypeOf(i); i && e(i); for (var a = XMLHttpRequest.prototype; a && !a.hasOwnProperty("addEventListener"); ) a = Object.getPrototypeOf(a); a && e(a) } else XMLHttpRequest.prototype.hasOwnProperty("addEventListener") && e(XMLHttpRequest.prototype); o.on("addEventListener-start", function(t) { if (t[1]) { var e = t[1]; "function" == typeof e ? this.wrapped = e["nr@wrapped"] ? t[1] = e["nr@wrapped"] : e["nr@wrapped"] = t[1] = r(e, "fn-") : "function" == typeof e.handleEvent && r.inPlace(e, ["handleEvent"], "fn-") } }), o.on("removeEventListener-start", function(t) { var e = this.wrapped; e && (t[1] = e) }) }, {1:15, 2:1, 3:14}], 4:[function(t) { var e = (t(3), t(1)), n = t(2); e.inPlace(window, ["requestAnimationFrame", "mozRequestAnimationFrame", "webkitRequestAnimationFrame", "msRequestAnimationFrame"], "raf-"), n.on("raf-start", function(t) { t[0] = e(t[0], "fn-") }) }, {1:15, 2:1, 3:14}], 5:[function(t) { function e(t) { var e = t[0]; "string" == typeof e && (e = new Function(e)), t[0] = n(e, "fn-") } var n = (t(3), t(1)), r = t(2); n.inPlace(window, ["setTimeout", "setInterval", "setImmediate"], "setTimer-"), r.on("setTimer-start", e) }, {1:15, 2:1, 3:14}], 6:[function(t) { function e() { o.inPlace(this, s, "fn-") } function n(t, e) { o.inPlace(e, ["onreadystatechange"], "fn-") } function r(t, e) { return e } var o = t(1), i = t(2), a = window.XMLHttpRequest, s = ["onload", "onerror", "onabort", "onloadstart", "onloadend", "onprogress", "ontimeout"]; window.XMLHttpRequest = function(t) { var n = new a(t); try { i.emit("new-xhr", [], n), o.inPlace(n, ["addEventListener", "removeEventListener"], "-", function(t, e) { return e }), n.addEventListener("readystatechange", e, !1) } catch (r) { try { i.emit("internal-error", r) } catch (s) { } } return n }, window.XMLHttpRequest.prototype = a.prototype, o.inPlace(XMLHttpRequest.prototype, ["open", "send"], "-xhr-", r), i.on("send-xhr-start", n), i.on("open-xhr-start", n) }, {1:15, 2:1}], 7:[function(t){function e(){function e(t){if ("string" == typeof t && t.length)return t.length; if ("object" != typeof t)return void 0; if ("undefined" != typeof ArrayBuffer && t instanceof ArrayBuffer && t.byteLength)return t.byteLength; if ("undefined" != typeof Blob && t instanceof Blob && t.size)return t.size; if ("undefined" != typeof FormData && t instanceof FormData)return void 0; try{return JSON.stringify(t).length} catch (e){return void 0}}function n(t){var n = this.params, r = this.metrics; if (!this.ended){this.ended = !0; for (var i = 0; u > i; i++)t.removeEventListener(s[i], this.listener, !1); if (!n.aborted){if (r.duration = (new Date).getTime() -
