JavaScript Object's Data Returns as Undefined

Trying to retrieve data from mongoDB using the find() function, which should return objects in an array format. However, encountering an issue where the desired data is not showing up in the array and instead returning undefined.

Here is the Object Array:

[
  {
    _id: new ObjectId("635fa2d24f33bf4626211990"),
    timestamp: '2022-10-30T08:41:06.826Z',
    content: 'something here',
    published: 'false'
  }
]
let data = await submissionSchema.find({ published: "false" }).exec();

The variable data holds the response retrieved from the database, containing the Object Array mentioned above. When using console.log(data[0]), everything displays correctly without the square brackets. But when accessing data[0].content, it returns undefined instead of 'something here' as expected. Any insights on this issue would be greatly appreciated.

Answer №1

After extensive investigation, I have finally pinpointed the source of the problem. Below, I will detail the issue in order to assist anyone else facing a similar dilemma.

Error Analysis:

const mongoose = require('mongoose');

const reqString = {
    type: String,
    require: true
}

const submissionSchema = mongoose.Schema({
    remark: reqString,
    published: reqString
})

module.exports = mongoose.model('submission-records', submissionSchema)

The root cause of the error lies in the omission of necessary data within the Schema. To rectify this bug, simply reintegrate the desired data back into the schema.

    const submissionSchema = mongoose.Schema({
        _id: reqString,
        timestamp: reqString,
        content: reqString,
        remark: reqString,
        published: reqString
    })
