Solution:-
These errors can be ignored as the issue will be addressed after the Web Tier is upgraded to 11.1.1.7 (11gR1 PS6) as a post-install step (see below).

Customers who have performed a fresh installation of EBS 12.2 must upgrade the Oracle Web Tier to 11.1.1.7 (11gR1 PS6) on the new 12.2 environment following the document:

• Upgrading Oracle Fusion Middleware Technology Stack of Oracle E-Business Suite Release 12.2 to 11.1.1.7 (11gR1 PS6) (My Oracle Support Document 1590356.1)
