Hi i am new here and using the railway server. i have a whatsapp node problem and it consist of 2 weird circumstances.
First is why is it my ‘send message whatsapp’ node is NOT working when the workflow is active but works when i am just testing it
1st screenshot
2nd screenshot
as you can see it consist of only 3 nodes.
- the trigger (1st screenshot is testing that works, 2nd screenshot is scheduled trigger that does not work)
- set fields node (to set the message)
- whatsapp send message node
the error message is:
{
“errorMessage”: “No execution data available”,
“errorDetails”: {},
“n8nDetails”: {
“itemIndex”: 0,
“runIndex”: 0,
“time”: “3/13/2025, 2:32:30 PM”,

]
}
}
SECOND CIRUCMSTANCE:
the error message for the whatsapp message node is "No execution data available
" as seen in screenshot no 2. even though there is a data there which is ‘{{ $json.body }}’ that maps from the previous ‘Set Fields’ node.
BUT when i hard code the message it to send a message directly in the text body in the whatsapp node, it works??? and i receive the message.
Any idea why?
i want the workflow to be active and send the message from the mapped output on the previous node
