page.js:387 Uncaught ReferenceError: _ is not defined

[akhilraj]

Hi,

We have migrated AEM Version from 6.3 to 6.5 SP10.

It was fine in DEV environment.

But When we deployed to Higher environment, we are getting below error in author whenever we will open page in edit mode.

The same error is coming in all the pages including we retail pages as well.

Path: /libs/cq/gui/components/authoring/editors/clientlibs/sites/page

page.js:387 Uncaught ReferenceError: _ is not defined
at page.js:387:339

Can someone please help. It is environment specific,.

@akhilraj it looks your code is not able to resolve the dependency on _.extent(...), check the below thread on the same kind of issue if it helps

Hi @akhilraj 

I have 6.5.10 in my machine it is working perfectly fine for me.

• By any chance are you overwriting anything under /libs?
• Can you check again in a fresh instance?

Thanks

Thanks Jeevan.

Issue was with upgrade only, we tried in fresh instance and it is working fine.

Tried to replicate with minification but didn't get this issue with my local AEM 6.5.10(we.retail).

No error message, with and without minification.
