NestJS and Apollo Federation: buildFederatedSchema is deprecated - graphql

Question

I am working with NestJS and Apollo Federation for a while and it seems that since last update I get
"(node:19113) DeprecationWarning: 'buildFederatedSchema' is deprecated. Use 'buildSubgraphSchema' instead."
I don't see a place where I could use buildSubgraphSchema and I didn't find anywhere from NestJS docs of Apollo Federation docs a way to remove this deprecated issue.
The full list of dependencies in my package json are
"dependencies": {
"#apollo/federation": "^0.33.3",
"#apollo/subgraph": "^0.1.2",
"#nestjs/common": "^8.0.0",
"#nestjs/config": "^1.0.2",
"#nestjs/core": "^8.0.0",
"#nestjs/graphql": "^9.1.1",
"#nestjs/mongoose": "^9.0.1",
"#nestjs/platform-express": "^8.0.0",
"apollo-server-express": "^3.4.0",
"class-transformer": "^0.4.0",
"class-validator": "^0.13.1",
"graphql": "^15.6.1",
"helmet": "^4.6.0",
"joi": "^17.4.2",
"mongoose": "^6.0.12",
"reflect-metadata": "^0.1.13",
"rimraf": "^3.0.2",
"rxjs": "^7.2.0"
},
The GraphQL module is defined in a file called graphql.module.ts with the following:
import { Module } from '#nestjs/common';
import { GraphQLFederationModule } from '#nestjs/graphql';
import { ApolloServerPluginInlineTraceDisabled } from 'apollo-server-core';
#Module({
imports: [
GraphQLFederationModule.forRoot({
plugins: [ApolloServerPluginInlineTraceDisabled()],
autoSchemaFile: true,
playground: true,
introspection: true,
buildSchemaOptions: {
dateScalarMode: 'isoDate',
},
context: ({ req }) => ({
jwt: req.headers.authorization,
}),
}),
],
})
export class GraphqlModule {}
Project still runs normally with the deprecated message but I would be keen to understand how to fix it.
Thanks in advance,

Based on Brando J answer, the next update of nestjs/graphql from version 9 to version 10 fix the issue

Answer 1

The cause of this warning comes from #nestjs/graphql v9 which still use "buildFederatedSchema" from #apollo/federation.
You can update to #nestjs/graphql v10 to get rid of that message. Also GraphQLFederationModule has been removed and replaced by GraphQLModule using ApolloFederationDriver.
tl;dr
update #nestjs/graphql to v10
