When I am trying to update just "title", it is working fine, but if I am trying to update the nested object in the array, it is not working.
Data: Data
Working:
const restaurant = await Restaurant.update(
{_id: '60e6828e4992a2979fa0ba3e'},
{$set: {title: "Hello}},
);
Not working:
const restaurant = await Restaurant.update(
{_id: '60e6828e4992a2979fa0ba3e', 'grades.grade': 85},
{$set: {'grades.$.grade': 0}},
);

Use $[]
The filtered positional operator $[] identifies the array elements that match the arrayFilters conditions for an update operation
db.collection.update(
{},
{ $set: { "grades.$[elem].grade": 0 }},
{ arrayFilters: [ {"elem.grade": 85 } ]}
)
