Mongoose can't find capital letter fields - node.js

Question

I have a schema in Mongo like this:
const userSchema = new mongoose.Schema({
_id: {
type: mongoose.Types.ObjectId,
required: true,
},
organizationId: {
type: mongoose.Types.ObjectId,
required: true,
},
projectsId: {
type: [mongoose.Types.ObjectId],
default: []
},
roleId: {
type: mongoose.Types.ObjectId,
required: true,
},
email: {
type: String,
required: true,
},
password: {
type: String,
required: true,
},
pic: {
type: String,
default: ''
},
createdOn: {
type: Date,
default: Date.now
}
I want to find users with a specific organizationId, but mongoose returns empty array. When i try to find with an _id, email it works but when i try it with organizationId and projectsId it doesn't find it. This led me to believe there is a problem with field names which have capital letters in them.
Here is my node/express code:
const getMemberListController = async (req, res, next) => {
try {
const memberList = await User.find({organizationId: '6239b5fc3c16a8041341a3e8'});
res.status(200).json(memberList);
} catch (error) {
res.status(500).json(error);
}
}
The above returns an empty array, eventhough
User.find({_id: '623ad5c75d17751ff664a9ae'})
returns:
[
{
"pic": "",
"_id": "623ad5c75d17751ff664a9ae",
"organizationId": "6239b5fc3c16a8041341a3e8",
"roleId": "ba3e35fc1341a80462c16398",
"projectsId": [
"6239b61f8f8e67d675297178",
"6239b637a4ec3ff5ef2df0cb"
],
"email": "yosephten#gmail.com",
"password": "$2a$10$hIMWjl2wz9g1C3NN4sqwHOMgx0epaJtdOmGVWckkRcCqltIn9JlTe",
"createdOn": "2022-03-23T10:42:11.170Z"
}
]
I tried it in mongoDB locally by running the same code: db.users.find({organizationId: '6239b5fc3c16a8041341a3e8'}) but this time, it returns the specified user.
I don't know if it is the capitalization or mongoose the issue. Please help.
Thanks.

Answer 1

Found it.
The issue was when i was creating users in db, i was using this script:
db.users.insertMany([
{
'organizationId': '3c16a8046239b5fc1341a3e8',
'roleId': 'ba3e35fc1341a80462c16398',
'email': 'yosephten#gmail.com',
'password': '$2a$10$hIMWjl2wz9g1C3NN4sqwHOMgx0epaJtdOmGVWckkRcCqltIn9JlTe'
},
{
'organizationId': 'b5fc3c16a80462391341a3e8',
'roleId': 'ba3e35fc1341a80462c16398',
'email': 'yoseph2#gmail.com',
'password': '$2a$10$hIMWjl2wz9g1C3NN4sqwHOMgx0epaJtdOmGVWckkRcCqltIn9JlTe'
},
])
But this will make the foreign key fields(organizationId roleId and projectsId) strings. Thus failing the check.
The script should be:
db.users.insertMany([
{
'organizationId': new ObjectId('3c16a8046239b5fc1341a3e8'),
'roleId': new ObjectId('ba3e35fc1341a80462c16398'),
'email': 'yosephten#gmail.com',
'password': '$2a$10$hIMWjl2wz9g1C3NN4sqwHOMgx0epaJtdOmGVWckkRcCqltIn9JlTe'
},
{
'organizationId': new ObjectId('b5fc3c16a80462391341a3e8'),
'roleId': new ObjectId('ba3e35fc1341a80462c16398'),
'email': 'yoseph2#gmail.com',
'password': '$2a$10$hIMWjl2wz9g1C3NN4sqwHOMgx0epaJtdOmGVWckkRcCqltIn9JlTe'
},
])
Now mongoose will check ObjectId to ObjectId instead of ObjectId to String.
