If you see the above stack then do the fix as suggested below

- Validate FND_NODES table for valid hostnames
- Validate FND_OAM_CONTEXT_FILES table for run and patch context file
- If a valid node does not have a valid run and patch context file in FND_OAM_CONTEXT_FILES , then it has to be loaded either by running autoconfig from the respective file system or if you do not want to run autoconfig then load the context file using API

$ADJVAPRG oracle.apps.ad.autoconfig.oam.CtxSynchronizer action=upload contextfile=$CONTEXT_FILE

Rerun ADOP Cycle.

Have fun with Oracle EBS 12.2
