Answer 1

This works on all versions on mongo, you need second argument for find,
db.myColl.update(
{
"user_id" : ObjectId("5c8109785b9a5427b167542a"),"permissions.app user listing":["insersssts"]
},
{
$set: {
"permissions.$.app user listing":["insertss"]
}
});

Try as below:
db.user_permission.update(
{
"user_id" : ObjectId("5c8109785b9a5427b167542a")
},
{
$set: {
"permissions.$[].app user listing": ['inserts']
}
},
{
upsert:false
}
)
Data before running query :
{
"_id" : ObjectId("5c98760c27b9fb1266f996b3"),
"user_id" : ObjectId("5c8109785b9a5427b167542a"),
"permissions" : [
{
"dashboard" : [
"Pie Chart",
"Bar Chart"
],
"product management" : [
"update",
"delete",
"list",
"insert"
],
"app user listing" : [
"insert",
"update",
"delete",
"list"
]
}
]
}
After running query:
{
"_id" : ObjectId("5c98760c27b9fb1266f996b3"),
"user_id" : ObjectId("5c8109785b9a5427b167542a"),
"permissions" : [
{
"dashboard" : [
"Pie Chart",
"Bar Chart"
],
"product management" : [
"update",
"delete",
"list",
"insert"
],
"app user listing" : [
"inserts"
]
}
]
}
