Faceted Search Filters not appearing in the UI

[Malarvizhi_Sara]

Hi Guys,

I have an issue in with the author instance in AEM 6.4 where I'm unable to see the Faceted search filter in the /content/dam and /content/sites section and when I checked for the console for logs

below is the error log,

I did the in-place upgrade from AEM 6.3 to AEM 6.4 and whereas the new instance of both AEM 6.3 and 6.4 It's working perfectly.

Any help on this is greatly appreciated! Thanks in Advance:)
