An APS task fails in POA with the error message Resource with UID 'UID' not found, like in the example below:
Resource with UID '671dc320-cd25-4527-b376-70d74e0798c6' not found.
A required entry with the UID provided in the failed task is absent from the POA database.
Upgrade POA to 5.4.12; the root cause of this issue has been fixed in this version.
Contact the Parallels Support Team to solve the problem for a particular failed task.
