Issues with migrating mbox.js to at.js

Level 4
Level 4

We started our migration from mbox.js to at.js and as first step we loaded the at.js through adobe target configuration which worked well. After loading the at.js in the page, we are receiving the following error


Uncaught ReferenceError: mboxFactoryDefault is not defined
at aam_tnt_cb (analytics_min.js:formatted:7031)
at event?d_stuff=1&d_dst=1&d_rtbd=json&d_cts=1&d_cb=aam_tnt_cb&d_dpid=604:1


From our understanding, mboxFactoryDefault is deprecated and not used in at.js.

In our analytics_min.js mboxFactoryDefault.getUrlBuilder() and other methods are throw errors.

Is there any way to replace the mboxFactoryDefault or other mboxFactoryDefault related methods with ones used in at.js.
Please help.

Thanks for your response.

Yes, we did follow the mentioned link.
But it did not help in the resolution of the errors which are coming up due to deprecated mbox.js methods.
I have post the same in Adobe Target community as well.

Hi @samsundar23 ,


Can you please let me know what you have done exactly as part of the migration? I have recently done migration of mbox.js to at.js and as part of that I have installed installed Adobe TargetV2 extension and modified the All Pages - Library loaded Launch rule, I just want to confirm if that's the right way?

I am seeing CQ_Analytics is undefined console error after doing this, that's the issue i am having right now

 Appreciate your response!!!
