This condition failure causes the exception.

frame.handle is null and the if condition is checking if(frame.handle != undefined)

Here is how the frame object looks like in the debug window

Object {size: 35, type: 0, channel: 0, performative: c}
VM255:1
channel:0
performative:c {value: Array(11)}
available:null
delivery_count:null
drain:null
echo:true
handle:null
incoming_window:5000
link_credit:null
next_incoming_id:1
next_outgoing_id:1
outgoing_window:2048
properties:null
value:Array(11) [Typed, Typed, Typed, …]
length:11
__proto__:Array(0) [, …]
0:Typed {type: TypeDesc, value: 1}
1:Typed {type: TypeDesc, value: 5000}
2:Typed {type: TypeDesc, value: 1}
3:Typed {type: TypeDesc, value: 2048}
4:Typed {type: TypeDesc, value: null}
5:Typed {type: TypeDesc, value: null}
6:Typed {type: TypeDesc, value: null}
7:Typed {type: TypeDesc, value: null}
8:Typed {type: TypeDesc, value: null}
9:Typed {type: TypeDesc, value: true}
10:Typed {type: TypeDesc, value: null}
__proto__:Object {dispatch: , next_incoming_id: <accessor>, incoming_window: <accessor>, …}
size:35
type:0
__proto__:Object {constructor: , __defineGetter__: , __defineSetter__: , …}

and you can rightly see that handle is null

What could be possibly happening?

[grs]

The check should be also checking for null. If the field is not specified at all (i.e. the performative is a list with largest index lower than the index for this field) it will be undefined, if however it is explicitly null, as it is here, that will fail the check but is essentially the same condition (i.e. flow is not associated with a particular link).

I've put in a more complete check; does that fix it for you?
