IE error handling

I use my own function for error handling

Global $o_AutoIt_MyErrFunc = ObjEvent("AutoIt.Error", "_AutoIt_MyErrFunc")

but when I use ie.au3   UDF then 

i have that message in console

 

--> IE.au3 V2.4-0 Warning from function internal function __IEIsObjType, Cannot register internal error handler, cannot trap COM errors (Use _IEErrorHandlerRegister() to register a user error handler)

 

so I try do that something

$oIEErrorHandler = $o_AutoIt_MyErrFunc
$sIEUserErrorHandler = '_AutoIt_MyErrFunc'

 

$o_AutoIt_MyErrFunc.windescription: Can't install a new Errorhandler when one is still active.

$o_AutoIt_MyErrFunc.description is:

$o_AutoIt_MyErrFunc.source is:

$o_AutoIt_MyErrFunc.helpfile is:

$o_AutoIt_MyErrFunc.helpcontext is: 0

$o_AutoIt_MyErrFunc.lastdllerror is: 0

$o_AutoIt_MyErrFunc.scriptline is: 3750

$o_AutoIt_MyErrFunc.retcode is: 0

 

Is there any way to use my errorhandler / my defined function used in ObjEvent for error handling from IE object ?
