Non-fatal error upon restart

After the upgrade to PG3 3.0.61 I gave the Node server a restart and noticed this error in the log during discovery:

2022-04-29 05:11:51,720 Command    udi_interface.interface ERROR    interface:_handleInput: _parseInput: failed d073d56be801.runCmd(SETB) list assignment index out of range

The Node server seemed to function just fine.  A second restart several minutes later did not result in this error.  I'm am not using a 'devlist.yml' file in this instance.
