UPPAAL Verification Error- Index value is out of range

Question

I am using Uppaal for system verification. The simulation is running perfectly fine but when I verify by using this property A[] not deadlock it is giving me the following error:

_The successors of this state are not well defined.
Index value 3 is out of range. Array length = 3, Element size = 1 in line 1 of go3[id]?_

What could have gone wrong there?

what is the type of go3 and what is the value of id? Uppaal is trying to tell that go3[3] does not exist. — mariusm, Sep 01 '18 at 12:24
go3 is an urgent channel, and I made a mistake in defining its array size. This's been sorted out now. Thanks!!! — Muhammad Hammad Saghir, Sep 02 '18 at 09:22

If your array has a length of 3 the index needs to be 0, 1, or 2. That's why index value 3 is out of range. Make sure your index is never bigger than arraylength-1.
