Which AEM version are you using?

Do you see the error while trying editing in Classic UI or Touch UI?


Level 3

Hi Rima,

Im using AEM 6.2. We are facing this issue in classic ui.

Any leads on this issue?

If you will include init.jsp(which brings on the sidekick), the error would go away.

Have this in your headlibs.html :

<sly data-sly-include="/libs/wcm/core/components/init/init.jsp" data-sly-unwrap/>

Hope this helps!

Try a fresh install of AEM and let us know if you see this error still. That will tell us if there is a bug or some action performed in your AEM instance that caused this.

hi smacdonald2008,

THis issue we are facing in all our environments like DEV,QA, STG and PROD. How could we install a fresh instance and check our code.We tried the same in local instance but whenever we deploy our code we are getting this issue.

You may need to include cq.jquery clientlib or tweak the clientLibs.

Can you share the URL of the page where I can reproduce ?

I just checked http://localhost:4502/cf#/content/geometrixx-gov/en/thankyou.html

i dont see any error.

Go to IE console and type CQ or $CQ, these should auto populate if they are available on the page.

Also try changing the order of the dependencies included in clientlib.
