get_monitor_association is not working for default monitor

This looks like a possible bug in iControl.

In Web UI you can navigate to Local Traffic/Nodes/Default Monitor to see the default node monitors. Trying to get the same using iControl:

 
 PHP5 
  
 $monitor_assoc=$soap->get_monitor_association(array(array('address_type'=>'ATYPE_STAR_ADDRESS',  
  'ipaddress'=>'0.0.0.0')));  
 

This is supposed to return the default node monitor - for example array("icmp"), however it crashes with this error instead:

 
 Exception caught in LocalLB::urn:iControl:LocalLB/NodeAddress::get_monitor_association() 
 Exception: Common: OperationFailed 
 primary_error_code : 16908342 (0x01020036) 
 secondary_error_code : 0 
 error_string : 01020036:3: The requested node address (none) was not found 
 

Environment - BIG-IP version 9.4.4. PHP5 with built-in SOAP extension (also tested this in C - same error appears there)
