Cant delete item from sqlite by qraphql mutation - sqlite

Question

I'm learning to write apollo server by following a graphql tutorial https://www.howtographql.com/graphql-js/3-a-simple-mutation/ but when I try to write a delete mutation and use it in the GraphQL Playground, I get null after executing, and if I check data in the Prisma studio there is no change
mutation delete and server response
I'm sure that there are many items for deleting also with current id which I used for delete
this is my code
prisma studio data
const {ApolloServer} = require('apollo-server');
const fs = require('fs');
const path = require('path');
const { PrismaClient } = require('#prisma/client')
const prisma = new PrismaClient()
const resolvers = {
Query : {
info: () => 'Info text',
feed: async (parent, args, context, info) => {
return context.prisma.link.findMany()
},
},
Mutation : {
post: (parent, args, context, info) => {
const newLink = context.prisma.link.create({
data: {
url: args.url,
description: args.description,
},
})
return newLink
},
delete: (parent, args, context, info) => {
const deleteLink = context.prisma.link.delete({
data: {
id: args.id
}
})
return deleteLink
}
}
}
const server = new ApolloServer({
typeDefs: fs.readFileSync(
path.join(__dirname, 'schema.graphql'),
'utf8'
),
resolvers,
context: {
prisma,
}
})
server
.listen()
.then(({url})=>
console.log(`Server is running on ${url}`)
);

I gat it. Instead data use where. Prisma supports filtering with where query option.
async function deleteLink(parent, args, context, info){
const deleteLink = context.prisma.link.delete({
where: {
id: +args.id,
}
})
}
