In AAP 2.5, Decision Environments on the EDA server do not use the exposed paths option in Settings => Jobs.  You have to change the option in a file on the EDA server which has to be redone after every update.

Request that the option to change the mounts for DE on EDA be exposed under Settings or in the installer via variable.  This will allow files to be shared with the DE more easily.

KCS for changing the file in 2.4:  https://access.redhat.com/solutions/7088769

The filename has changed to /etc/ansible-automation-platform/eda/settings.yaml
