Description
In case of a removeMany with a filter query that returns no items, with mongoose v5 I got a success with deletedCount: 0
. But with mongoose v6 I get an Error with the message {"acknowledged":true,"deletedCount":0}
.
I have investigated and here is the issue:
await beforeQueryHelper(resolveParams)
returns:
- With mongoose v5:
{ n: 0, ok: 1, deletedCount: 0 }
. - With mongoose v6:
{"acknowledged":true,"deletedCount":0}
Steps to Reproduce
With mongoose V6, do a mutation with a filter that match no items like
await client.mutate({
variables: {ids: []},
mutation: gql`
mutation yourEntity($ids: [String]!) {
removeMany(filter: {
_operators: {
_id: { in: $ids }
}
}) {
numAffected
}
}
`
})
Expected Behavior
I expect the same behaviour than with mongoose v5: getting a success response { n: 0, ok: 1, deletedCount: 0 }
They mentioned the change in mongoose v6 in the doc here: https://mongoosejs.com/docs/migrating_to_6.html#mongodb-driver-40
