const task = await taskCollection.find({
_id,
'attachments._id': as string),
});

db-accessor:
export const find = async (query = {}, sortOptions = {}): Promise<ITaskCollection[] | null> => {
query);
return db.notaryTaskCollection
.find(query)
.sort(sortOptions)
.catch((err: Error) => {
logger.error(err);
return null; // Return null on error instead of an empty array
});
};

[
{
_id: new ObjectId('6724ce9634f2433de715065a'),
taskName: '',
attachments: [ [Object], [Object], [Object], [Object] ],
createdAt: 2024-11-01T12:50:30.286Z,
updatedAt: 2024-11-01T12:50:30.286Z,
__v: 0
}
]

attachments: [
{
fileName: 'test.pdf',
filePath: '',
uploadDate:,
uploadedBy:,
_id: new ObjectId('6724ce9634f2433de715065b'),
notes: []
},
]

its returing all attachments object, filtering is not working
