Hello!
I am trying to retrieve a variable with a null value from a FunctionItem node , however, the variable is not displayed to me in the subsequent HTTP Request node .
I realize that this only with variables with null value, but I want to redeem them anyway, when these variables contain null value, I need to send null in the request.
How do I solve this problem?
Regards,
@guilhermeagirardi Welcome to the community.
Just tested it and you are right it seems like a bug.
@jan can be replicated with the example below.
{
"nodes": [
{
"parameters": {},
"name": "Start",
"type": "n8n-nodes-base.start",
"typeVersion": 1,
"position": [
250,
300
]
},
{
"parameters": {
"functionCode": "items[0].json.variable = null;\nreturn items;"
},
"name": "Function",
"type": "n8n-nodes-base.function",
"typeVersion": 1,
"position": [
480,
300
]
},
{
"parameters": {
"requestMethod": "POST",
"url": "https://webhook.site/49dfc658-d5d6-4a06-8da5-79ae1b65340d",
"options": {},
"bodyParametersUi": {
"parameter": [
{
"name": "value",
"value": "={{$node[\"Function\"].data[\"variable\"]}}"
}
]
}
},
"name": "HTTP Request",
"type": "n8n-nodes-base.httpRequest",
"typeVersion": 1,
"position": [
680,
300
]
}
],
"connections": {
"Start": {
"main": [
[
{
"node": "Function",
"type": "main",
"index": 0
}
]
]
},
"Function": {
"main": [
[
{
"node": "HTTP Request",
"type": "main",
"index": 0
}
]
]
}
}
}

Sorry do not understand. But should not make a difference for you. It should only solve a bug that before did error when “null” got returned.
