Mongoose aggregation With GraphQL returning error - node.js

Question

I'm working on a project and currently using Mongodb Time-Series and aggregation.
I connected my Apollo Graphql to retrieve the data but i'm stuck with an error that i can not solve no matter what.
Float cannot represent non numeric value:
On my db the numbers are saved as Double. If i try to run the query in MongoDB Aggregation with MongoDBCompass it's working perfectly but not on my Nodejs database.
I tried googling my problem first and looking ad docs but all the different solution i found do not solve my problem, any suggestions?
This is my Query:
module.exports = async (root, { limit }, { models }) => {
const keyx = await models.Weather.aggregate([
{
$group: {
_id: {
yearMonthDay: {
$dateToString: { format: "%Y-%m-%d", date: "$timestamp" },
},
},
temp: {
$push: { temp: "$temp" },
},
},
},
])
.exec();
return keyx;
};
This is my model:
const mongoose = require("mongoose");
const { Schema } = mongoose;
mongoose.pluralize(null);
const weather = new Schema({
timestamp: {
type: String,
trim: true,
},
temp: {
type: Number,
trim: true,
},
});
const Weather = mongoose.model("time_weather", weather);
module.exports = { Weather };
and this is my types:
const { gql } = require("apollo-server");
module.exports = gql`
type Weather {
timestamp: String
_id: ID
temp: Float
}
type Query {
weather(limit: Int): [Weather]
}
`;
and finally this is the response i'm getting from apollo studio:
{
"errors": [
{
"message": "Float cannot represent non numeric value: [{ temp: 11.7 }, { temp: 11.7 }, { temp: 12.01 }, { temp: 13.21 }, { temp: 13.21 }, { temp: 11.93 }, { temp: 13.21 }, { temp: 12.73 }, { temp: 14.21 }, { temp: 11.7 }, ... 14 more items]",

},
