As the error suggests, you need to have double quotes around all the values.
Moreover, this wont work “{ “CreationDate”: { “$lte”: new Date(new Date().getTime() - 1000 * 3600 * 24 * 365) } }”

You need to use the correct syntax, something like below

{
"$and": [
{ "Result": { "$ne": "null" } },
{ "$lte": [
    "$CreationDate",
    { "$subtract": [ "$$NOW", 31536000000 ] }
  ] }
]
}
