RDS Mysql Minor Upgrade Failed

Question

Problem:- On AWS account 6587xxx, tried RDS instance(lcxx-rds) upgrade from 8.0.28 to 8.0.35. Unfortunatley, upgrade doesnt went through, giving an error as
			"Database instance is in a state that cannot be upgraded: PreUpgrade checks failed: RDS detected incompatibilities when upgrading to MySQL 8.0.35. For                    details, see the PrePatchCompatibility.log file in the Logs section."
			However, the log doesnt show up the PrePatchCompatibility.log file.
			Rds Instace type :- Multi-AZ
			Read-replica(lc-prxx-rds) successfully upgraded.
                       How we can get the log file and get it upgraded to 8.0.35?			
		
Expected behavior:- Since, its minor version, upgrade should happen to 8.0.35.

Answer

In the AWS RDS console there is a 'events and logs' tab. The PrePatchCompatibility.log will be there.
