Nested filter always returns all entries

I try to filter by a nested field of type boolean. Autosuggestion works fine, but the filter does nothing. All records where shown in the results.

```
{
pages(filter:{response:{hasErrors:true}}) {
projectID
url
session
response {
hasErrors
status
headers
}
}
}
```

schemaComposer looks like that:

```
schemaComposer.Query.addFields({
pages: PagesTC.mongooseResolvers.findMany(),
page: PagesTC.mongooseResolvers.findOne(),
})

const graphqlSchema = schemaComposer.buildSchema()
export default graphqlSchema
```
