$flow.state in Agentflows is undefined in Flowise v 3.0.0

[engmsalem]

$flow.state is undefined in Flowise v 3.0.0, when I tried to use state as a counter , it doesn't work when I tried to try something like :
{{$flow.state.loop_counter}}+1 in the UI but it act as string "0"+1==> 01

• when I tried to do the same in a Custom Function:
  const state= $flow.state ;
  console.log('state:',state); ===> state is undefined.

I feel it's memory issue, although memory is enabled and states are defined in the start node.
if I use UI and assign it fixed value works fine other but to increment it doesn't.

Any idea?
