no need to change but this is equivalent to 'permissionList.read': { $exists: true }

})

{
// Number of objects in permissionList with read key - expect 0 after running update
const permissionListWithReadKey = [
{
$match: {
permissionList: { $elemMatch: { read: { $exists: true } } }

db.getCollection('forms').aggregate(permissionListWithReadKey)

// Update - Remove read key
db.forms.update(

again no need to change but this is equivalent to this:

Suggested change
{ $unset: { 'permissionList.$[elem].read': 1 } },
{ arrayFilters: [{ 'elem.read': { $exists: true } }], multi: true }
{ $unset: { 'permissionList.$[].read': 1 } },
{ multi: true }

)


// Check again, should be 0.
db.forms.count({
permissionList: { $elemMatch: { read: { $exists: true } } }
})

// Check again, should be 0
{
// Number of objects in permissionList with read key - expect 0 after running update
const permissionListWithReadKey = [
{
$match: {
permissionList: { $elemMatch: { read: { $exists: true } } }
},
},
{ $project: { permissionList: 1 } },
{ $unwind: '$permissionList' },
{ $match: { 'permissionList.read': { $exists: true } } },
{ $count: 'numObjs' }
]

db.getCollection('forms').aggregate(permissionListWithReadKey)
}
