Same error on Magento 2.4.6-p6

[mrafyq]

Same error on Magento 2.4.5-p10

[usuyukiso]

reproduced for me on 2.4.7-p3. It is only reproduced with New Relic installed.

[MagePsycho]

Same issue on Magento 2.4.5-p2. It is only reproduced with New Relic installed. Got it fixed by using the legacy-build js file from Magento 2.4.7-p1 (still yet to check it's consequences)

[bbrigagao]

I saw this error after updating projects to the bulletin APSB24-61 on projects with New Relic configured.

If you guys check the release notes there was a fix on prototype js scripts (I don't know if could be related to this).

There are 3 types of New Relic accounts and the script will be injected according to your account:

Lite - https://js-agent.newrelic.com/nr-rum-1.267.0.min.js Pro - https://js-agent.newrelic.com/nr-full-1.267.0.min.js SPA (pro + spa) - https://js-agent.newrelic.com/nr-spa-1.267.0.min.js

I saw this error only happens on projects that have SPA accounts, perhaps it could be an incompatibility with this SPA script.

[pjw345]

I've checked the bulletin and have not seen anything regarding legacy-build.min.js.

@bbrigagao can you remember where you read that or did I miss it?

[pisicabogdan]

Again, same error on Magento 2.4.6-p7 (last week upgraded from 2.4.6-p6).

[bbrigagao]

@pjw345 I found that the legacy-build.min.js is related to prototype js on this issue. So, I suspected that could be related to this since on bulletin APSB24-61 there was a fix on prototype js scripts.

Hi Adobe Commerce Support, same problem with Magento (2.4.7-p3) and not have problem with preview (2.4.7-p2) hosted in Magento Cloud.

Where i have this problem in Admin Panel :

• Catalog / Add product, Edit Product
• Catalog / Categories
• Sales / Orders, Invoices, ..
• Content / Edit Page CMS, Block CMS
• Stores / Configuration

Uncaught TypeError: this._each is not a function at e (legacy-build.min.js:1:14513) at nr-spa-1.268.0.min.js:2:83492 at Array.forEach (<anonymous>) at y.ce [as onFinished] (nr-spa-1.268.0.min.js:2:83471) at b.finish (nr-spa-1.268.0.min.js:2:78433) at nr-spa-1.268.0.min.js:2:78006

File from vendor lib (legacy-build.min.js) = [...] var Enumerable = (function() { function e(E, D) { try { this._each(E, D) [...]

Cordialement, Matthew Lafrance

I believe the issue can be resolved by fixing the legacy-build.min.js file directly. According to this ticket - https://github.com/newrelic/newrelic-browser-agent/issues/1201, it appears that the legacy JavaScript is overriding Object.values(), which is causing the problem.

Please let us know if the Magento team or any of you have identified a permanent fix.

[stefancic]

Same error on 2.4.4-p11, was not on 2.4.4-p4.

[alexgalco]

Confirmed on 2.4.7-p2

[pisicabogdan]

Changed legacy-build.min.js with the version from 2.4.6-p5 but with no effect; the problem isn't from legacy-build.min.js

[pjw345]

Changed legacy-build.min.js with the version from 2.4.6-p5 but with no effect; the problem isn't from legacy-build.min.js

We are running 2.4.7-p2 and replaced the legacy-build.min.js with the version of 2.4.7-p1

ACP2E-3375: [CLOUD] In admin there are many javascript error in console probably fixes this problem.

[jonaschen623]

adobe has an official patch for this issue, please raise a support ticket. Below one is for magento 2.4.6 ACSD-62427_2.4.6-p7.patch

[stefancic]

None of last two patches fix this.

[lamasfoker]

@stefancic the patch provided by @hostep and @jonaschen623 it's working. You need to apply this change to legacy-build.min.js:

  n(Object, {
    extend: n,
    inspect: r,
    toJSON: g ? Q : H,
    toQueryString: J,
    toHTML: v,
    keys: Object.keys || E,
-    values: N,
+    values: Object.values || N,
    clone: z,
    isElement: L,
    isArray: B,
    isHash: y,
    isFunction: t,
    isString: l,
    isNumber: M,
    isDate: A,
    isUndefined: u
  });

You can apply the following patch with Quality Patches Tool. It is tested on Adobe Commerce Cloud 2.4.6-p7. issues-39247.patch

Hi @pjw345 Is there any fix to this bug?

[pjw345]

@bohdanbatsenko as previously stated, replacing the legacy-build.min.js with the version of 2.4.7-p1 appeared to resolve the issue

[jtolhurst-trellis]

Replacing legacy-build.min.js with the version found in 2.4.7-p1 resolved the error for me. Waiting on an official fix.

[hostep]

ACP2E-3375: [CLOUD] In admin there are many javascript error in console probably fixes this problem.

Another extra change made it in the codebase today: ACP2E-3459: Request for additional changes to fully complete the ACP2E-3375 fix

No idea if this will do anything in scope of this ticket...
