Unable to load inventory nodes due to vault parsing error

Since the update from Rundeck v5.2.0 to v5.5.0, nodes cannot be loaded because reading vault files fails:

Running the playbook without rundeck works as expected (same host as rundeck).

When downgrading to rundeck v5.2.0 everything works as expected.

no change with the current Rundeck version v5.6.0 :(

Unfortunately, the problem still exists with the current plugin version v4.0.6.
