Jquery is not a valid asset group handle

I am seeing the following notice in the site log…

ResponseAssetGroup::requireAsset required “jquery/ui” but “jquery/ui” is not a valid asset group handle

The theme I am using is a few years old but still appears to be working fine. Is there something that might be clashing with 9.3.3 ?

I just can’t seem to be able to clear this error notice.

It looks like your theme is trying to call a deprecated asset, Hissy has answered the same question here…

Thank you. Yes, I have just seen Hissy’s answer to a similar question. It is just trying to work out what is causing the issue including add-ons ? Although the current add-ons I have installed appear to be up-to-date and compatible with 9.3.

The logging of the ‘not a valid asset’ does not necessarily prevent an addon from working.

A developer could have left the requireAsset in their code:

  • To preserve backward compatibility with v8
  • Because they tested and it didn’t break under v9

There are quite a few addons/themes that continue to do such. The old v7/v8 file manager is a frequently logged missing asset.
