Can you try this, just to see if it will give you NameError: name 'next_action' is not defined or NameError: name 'sender_id' is not defined?
data = {
"sender_id": "default"
"next_action": "action_notify_data_changed",
}
res = requests.post('http://localhost:5055/webhook/', data=json.dumps(data))
Also, since you’re doing it with Python, make sure the keys are enclosed within " ".
Can you also try it using Postman?
after adding " " NameError is gone, but now I got the other error.
My code is like this,
class ActionSessionStart(Action):
def name(self) -> Text:
return "action_session_start"
async def run(self, dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
client = Client(url='opc.tcp://141.82.166.100:4840/freeopcua/server/')
client.connect()
node = client.get_node("ns=2;i=2")
print('#########################initial value=', node.get_value(),'###############################')
handler = SubscriptionHandler(dispatcher)
# We create a Client Subscription.
subscription = client.create_subscription(500, handler)
nodes = [
node,
]
# We subscribe to data changes for two nodes (variables).
subscription.subscribe_data_change(nodes)
return []
class SubscriptionHandler():
def __init__(self, dispatcher) -> None:
self._dispatcher = dispatcher
def datachange_notification(self, node: Node, val, data):
print('@@@@@@@@@@@@@@@@@datachange_notification %r %s' %(node, val),'@@@@@@@@@@@@@@@@@')
self._dispatcher.utter_message(text=('datachange_notification %r %s' %(node, val)))
data = {
"sender_id": "default",
"next_action": "action_notify_data_changed",
}
res = requests.post('http://localhost:5055/webhook/', data=json.dumps(data))
print(str(res.status_code) + " | " + res.text)
class AtionNotifyDataChanged(Action):
def name(self) -> Text:
return "action_notify_data_changed"
async def run(self, dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
dispatcher.utter_message(text=("🛑Warning! test value is 0!"))
And I got an error like this:
Exception occurred while handling uri: 'http://localhost:5055/webhook/'

<h1>⚠️ 500 — Internal Server Error</h1><p>The server encountered an internal error and cannot complete your request.
Yes, I also tried in Postman, but it also have an error like this:
Cloud Agent Error: Can not send requests to localhost. Select a different agent.
Wait… you’re sending the POST request from a custom action? Why?
You’re doing this to trigger a custom action, but then what would trigger the trigger if it is a custom action itself?
I don’t know what your data that changes is, but whenever it happens, you should execute the POST request from outside of Rasa.
Also make sure default is a sender ID that exists.
Anyway, again, try sending the request from Postman to see what happens.
To post to custom action use following format
{
next_action: "action_notify_data_changed",
"tracker":{"sender_id":"user123"}
}
