How to print custom message in GraphQL - mongodb

Question

Hi I am working with GraphQl with the combination of es6.
While removing a particular record from graphql, I am getting details(values) of the deleted record, I want to print some custom message like "Record deleted". Please help me accordingly.
Here is my graphQL code:
removeUser:{
type: UserType,
args: {
_id: {
description: 'The _id of the user',
type: GraphQLString,
},
},
resolve: (obj, {_id}) =>{
return new Promise((resolve, reject) => {
User.findOne({_id:_id},(err,res)=> {
if(err || res == null) {
reject('User was not found')
}
else {
User.remove({_id: _id},(err,result)=>{
err ? reject(err) : reject('User removed successfully')
});
}
})
})
}
}

You declare UserType as the type of the removeUser field. Obviously, the string 'User removed successfully' is not a UserType; it's a String type.
Also, if the delete operation is successful, you should call resolve in the Promise, not reject.
I think something like this should work:
removeUser:{
type: GraphQLString,
args: {
_id: {
description: 'The _id of the user',
type: GraphQLString,
},
},
resolve: (obj, {_id}) =>{
return new Promise((resolve, reject) => {
User.findOne({_id:_id},(err,res)=> {
if(err || res == null) {
reject('User was not found')
}
else {
User.remove({_id: _id},(err,result)=>{
err ? reject(err) : resolve('User removed successfully')
});
}
})
})
}
}
