For customers below APP10 UPD 10 , when opening Aurena client pages, below error can be observed in the console

Error stack:
Cannot read property 'nativeElement' of undefined
TypeError: Cannot read property 'nativeElement' of undefined

This issue will be solved by LCS bug id 156817 which is a framework group patch  included in UPD 11.

However as per the R&D recommendations, this patch should be applied along with either UPD 10 or UPD 11 and cannot apply as a single patch.
