Hello I’m trying to create a user in my mongo DB.
Every time I try mongoDb returns :
[
{
"userHash": null,
"email": null,
"_id": "6012a4e9bba21a2590ba4a7b",
"id": "6012a4e9bba21a2590ba4a7b"
}
]
If I use the code in this answer the code works well : Mongodb query
But If i’m trying to adapt the code to my use case it doesn’t works properly.
Here is what I created :
{
"nodes": [
{
"parameters": {},
"name": "Start",
"type": "n8n-nodes-base.start",
"typeVersion": 1,
"position": [
130,
-380
]
},
{
"parameters": {
"functionCode": "const keyNeeded = ['userHash', 'email'];\nvar gotAllNeededKey = false;\n\nconst result = [];\n\nif (items[0].json.body) {\n if (Object.keys(items[0].json.body).length == keyNeeded.length){\n \n gotAllNeededKey = true;\n const body = items[0].json.body;\n \n for (let i=0; i < keyNeeded.length ; i++){\n if(!body[keyNeeded[i]]) {gotAllNeededKey = false;} \n }\n }\n}\n\nresult.push({ json: { requestIsValid: gotAllNeededKey, body: items[0].json.body} });\n\nreturn result;\n"

Any idea why it doesn’t works ?
