Do you want to continue with the prepare phase [Y/N] ?

We run adop prepare using variables for the passwords:

{ echo $APPS_PW; echo $STM_PW; echo $WLSADMIN_PW; } | adop phase=prepare

However this fails as additional input is required when a DR site exists for the DB. The following error is seen:

[WARNING] adop has detected a configured disaster recovery site.
[WARNING] Follow the instructions in the section "Oracle E-Business Suite
[WARNING] Maintenance with Standby Database" of Business Continuity for
[WARNING] Oracle E-Business Suite Release 12.2 depending on the database version used.
Do you want to continue with the prepare phase [Y/N] ?

adop exiting with status = 2 (Fail)

Patch 21878338 Required to fix the ADOP issues in a Data Guard Configuration was tried but did not fix the issue.
